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.

about push button switches

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.

Level switches

Liquid level sensing devices are often used to indicate the level of liquid in a vessel or other container and/or to operate flow control devices that control the liquid level. The level detection is based on different principles. There are known mechanical, electromechanical and hydrostatic level switches, ultrasonic level switches, capacitive and conductive level switches, microwave level switches, optical and radiometric level switches. Mechanical and electromechanical level switches are suitable for liquids only. Mechanical and electromechanical level switches usually incorporate a float buoy for sensing the fluid level, the float buoy being operatively connected to a switch device. The electrical switch is actuated upon physical movement of the portion of the float switch device containing the electrical switch or upon physical movement of another portion of the float switch device. A capacitance point level switch is operable to sense a specific level of the material in the vessel and provide a discrete output, such as with a relay contact, when the material is at a sufficient level to cause the capacitance between the probe and the reference to exceed a reference value. The capacity of the measuring capacitor within a sensor varies according to the surface level displacement of the material contained in a tank.

snap action switches

Electrical snap action switches operate on the arched elastic sheetmetal member principle, and provide snap actions in response to changes in pressure exerted upon the arch. A conventional snap action switch conducts upon mechanical contact between a metal snap action plate and metal pins (or conductors on a printed circuit board). In such a snap action switch, switch closure is recognized by detecting an electrical short between pins. Pneumatic snap action switches have a diaphragm and two or more electrical contacts arranged inside the switch body and sealed by the diaphragm so that upon a particular pressure being applied the internal contacts close and the switch performs its desired function. A subminiature snap action switch is characterized by an actuator lever which causes a coil spring in a pivot bracket assembly to open or close a pair of electrical contacts. Single pole snap action dome or oil can switches have been used to provide reliable electrical switch contacts in relatively low-current apparatus, for example electronic calculators or computers. Such switches have typically utilized a dome-shaped switch element to make and break electrical contact with an associated underlying conducting contact.
