Toggle-switches

Electronic switch can be visualized as a group of one or more mechanical electrical switches in which,instead of mechanically opening or closing the contacts, the physical opening and closing is achieved by applying appropriate electrical control signals to separate terminals on the switch in much the same way that a relay performs.A toggle switch is a class of electrical switches that are actuated by a mechanical lever, handle,or rocking mechanism.It is a switch that uses a toggle joint with a spring to open or close an electric circuit as an attached lever is pushed through a small arc.Toggle switches are available in many different styles and sizes,and are used in countless applications.Many are designed to provide,e.g.,the simultaneous actuation of multiple sets of electrical contacts,or the control of large amounts of electric current or mains voltages.

Detector-Switches

Switch is an electrical component that can break an electrical circuit, interrupting the current or diverting it from one conductor to another.The most familiar form of switch is a manually operated electromechanical device with one or more sets of electrical contacts. Each set of contacts can be in one of two states: either ‘closed’ meaning the contacts are touching and electricity can flow between them, or ‘open’, meaning the contacts are separated and nonconducting.Elecsound can offer series of switches,including toggle switch,Bottom Slide Switch ,Leaf Switch ,Tact Switch ,Vertical Push Switch ,Multi Function Switch ,Micro Switch ,etc.Detector Switches are used to detect internal mechanical movements and convert those or human manual operations, such as the closing of a flip-phone, to electronic signals.

Rocker-switch

A rocker switch is an on/off switch that rocks when pressed, which means one side of the switch is raised while the other side is depressed much like a rocking horse rocks back and forth. A rocker switch may have a circle on one end and a horizontal dash or line on the other to let the user known if the device is on or off. Rocker switches are used in surge protector s, display monitors, computer power supplies, and many other devices and applications.A rocker switch with independent circuitry can have a light activated on the face of the switch in both the on and off positions, which allows the switch to be found easily in the dark.With dependent circuitry, the light is activated only when the switch is on.Rocker switches are the perfect choice for economical, compact switching, in current ratings up to 20 amps.They’re available in a wide variety of colors, in both lighted and non-lighted designs. Lighted switches include both neon and incandescent bulbs for AC or DC lighting.

Leaf-switch

Leaf switch is an electric switch with a button (or other moving part) and two strips of metal that make contact when the button is pushed.Leaf switch consists of a piece of stainless steel tubing with a plastic tip onto which a foam pad can be inserted. The leaf switches is a two-way deflecting switch. It has a soft, red vinyl, non-abrasive casing.It is activated by pressing lightly against the leaf in one direction and comes with a removable 3″ round foam pad.It is made of high quality materials and with reliable performance, different sizes are available.The leaf switch is enclosed in a soft, non-abrasive vinyl sleeve so it can be used in tight access areas, such as between the upper arm and the chest, or under the chin.

Push-button-switch

A push button switch is used to either close or open an electrical circuit depending on the application. Push button switches are used in various applications such as industrial equipment control handles, outdoor controls, mobile communication terminals, and medical equipment, and etc. Push button switches generally include a push button disposed within a housing. The push button may be depressed to cause movement of the push button relative to the housing for directly or indirectly changing the state of an electrical contact to open or close the contact. Also included in a pushbutton switch may be an actuator, driver, or plunger of some type that is situated within a switch housing having at least two contacts in communication with an electrical circuit within which the switch is incorporated.

Slide-switches

Slide switches are mechanical switches defined by their method of activation. The switch is a slider that moves (slides) from position to position. Slide switches are known for providing selection of two or more switch positions for engagement of respective switch contacts. Electrical slide switches have long been used to control the operation of many devices, including volume and other controls for audio & video equipment, dimmer controls for lights among a multitude of other daily electrical products. Such slide switches have also been used for controlling the operating speed of many kinds of variable speed hand tools. In electrical slide switches a slide member is slidably repositionable to affect a switching action. Slide switch operation can occur in conjunction with pushbutton operation to provide momentary pushbutton switch actuation in each of the slide switch positions. Slide actuated switches come in a variety of forms. A commonly used slide switch has a strip of conductor material mounted on a slider and fixed contacts connected to terminals of the switch mounted in a body. Movement of the slider relative to the body moves the strip of conductor material into and out of contact with the fixed contacts to provide a switching action. Another type of slide actuated switch relies upon the slider movement causing a pivoting movement of a conductor member from one to the other of two extreme positions.

Hook-Switch

The hookswitch was identified as on and off switch for most operations of a telephone. The hookswitch consisted of seven metallic leaves, a notched fiber board, spring and an insulated base which was, as one unit semi-permanently mounted with rivets to the base of the telephone instrument. Eavesdroppers could easily modify the hookswitch so that it could pass audio from the handset down the telephone line even though the handset was setting on the instrument’s cradle. Electronic hook switches are more commonly used in high volume telephone and DAA products because they offer lower cost than relays, consume less power, and are smaller. However, electronic hook switches are constructed from high voltage transistors and have difficulties being driven from integrated circuits fabricated in low voltage processes. One difficulty is that the control current available on a DAA integrated circuit (IC) is very low. Another difficulty is that often at least one transistor is required to high voltage level shift control outside of the operating voltage range of the controlling circuit. Collectively, level shifting and cascading of transistors to get sufficient current gain typically require the use of at least 3 high voltage, bipolar transistors.

Electrical-switches

Electrical switches are devices utilized to manually control electric current flow. Manually operated switches include an actuator used to cause making/breaking action of switch contacts to energize or de-energize one or more electrical circuits associated with the contacts. In addition to switching electrical signals responsive to physical actuation of the switch, electrical switches may include actuation indication including tactile feedback or audible feedback. Switches are available that are equipped with lamps used for helping people find the switches in the dark. There are several different types of light switches. Common switch types include rocker, toggle, push button, rotary, keylock, slide, snap action and reed switches. Switches are highly varied based on their intended utility. In electromechanical systems, switches provide the function of making and breaking electrical contacts and consequently electrical circuits. Switches responsive to fluid levels have utilized a variety of approaches for opening and closing an electrical circuit. Switches have found particular use in industrial control systems, where it is often desirable to monitor conditions so that appropriate actions may be taken in response to the monitored conditions.

A push button switch is used to either close or open an electrical circuit depending on the application. Push button switches are used in various applications such as industrial equipment control handles, outdoor controls, mobile communication terminals, and medical equipment, and etc. Push button switches generally include a push button disposed within a housing. The push button may be depressed to cause movement of the push button relative to the housing for directly or indirectly changing the state of an electrical contact to open or close the contact. Also included in a pushbutton switch may be an actuator, driver, or plunger of some type that is situated within a switch housing having at least two contacts in communication with an electrical circuit within which the switch is incorporated. Typical actuators used for contact switches include spring loaded force cap actuators that reciprocate within a sleeve disposed within the canister. The actuator is typically coupled to the movement of the cap assembly, such that the actuator translates in a direction that is parallel with the cap. A push button switch for a data input unit for a mobile communication device such as a cellular phone, a key board for a personal computer or the like is generally constructed by mounting a cover member directly on a circuit board. Printed circuit board (PCB) mounted pushbutton switches are an inexpensive means of providing an operator interface on industrial control products. In such push button switches, a substrate which includes a plurality of movable sections is formed of a rubber elastomer. The key top is formed on a top surface thereof with a figure, a character or the like by printing, to thereby provide a cover member. Push button switches incorporating lighted displays have been used in a variety of applications. Such switches are typically comprised of a pushbutton, an opaque legend plate, and a back light to illuminate the legend plate.

toggle-switches

A toggle switch is a switching device comprising a plurality of terminals and means operated by a projecting leve for making and breaking electrical connections between pairs of those terminals. Toggle switches of various types have long been used to control power in domestic, commercial, industrial, and military applications for operating various electrical devices and equipment. Toggle switches typically are manufactured with a dielectric housing that contains electrical contacts and is fitted with a manually operable handle to switch power to externally mounted terminals. Toggle switches typically provide a manually accessible member which has metastability in a first position and a second position. A toggle switch includes a toggle lever that is mounted to a cover or housing so as to pivot about an axis or the like. A spring is placed in contact with the toggle lever to exert a biasing force to maintain the toggle lever in one or more stable positions, in addition to maintaining or assisting in the maintenance of a force on electrical contacts that are being switched into contact.
