Rocker-switches

A rocker switch is a device having a plurality of terminals and means operated by a rocker for making and breaking electrical connections between pairs of those terminals. A rocker switch includes a button that is mounted to a case to pivot about an axis. A spring is typically placed in contact with the button to exert a biasing force that will maintain the button in one or more of the stable positions. The plunger operates a rocker actuator by a force exerted from the spring. The spring also supplies the force that causes the switch to toggle from one stable position to another. In general, the rocker switch is constructed such that its switch components or parts are housed in a square or rectangular housing the top of which is open and an operation button is mounted at the opening space of the box at the top thereof such that it can be moved for seesaw movement. The rocker switches are used in various kinds of OA machines, amusement and game machines, measurement instruments, and medical instruments.

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.

Foot-switches

Many types of machinery are operated by switches adapted to be actuated by the foot of the machine operator. Foot operated switches for controlling the application of electrical power to external electrical circuits are widely employed in industry. For example, foot switches are often used to trigger the delivery of laser energy in a medical laser system. Foot actuated pneumatic switches are often used in the food equipment industry to obtain precise hands-free operation of the desired food equipment, such as a meat mixer-grinder. The conventional type of foot switch generally comprises a pressure-contact switch disposed in a vertical position and directly controlled by a pressure cap to connect or disconnect electricity. Foot operated switches generally use mechanical or pneumatically actuated switches. Mechanically actuated foot switches are typically either of the plunger or push button type, or the tumbler type. Pneumatically actuated foot switches usually comprise a deformable pneumatic bulb, or air cushion, which is deformed by the foot of the user to operate a remotely located switch mechanism. When depressed, the actuator creates a burst of pressurized air which passes through a hose, tubing or other path to flip a pressure operated switch thereby initiating operation of a piece of equipment. A typical foot switch comprises a base carrying a switch having at least one electrical contact which is capable of moving between an open position and a closed position upon depression of a pedal member pivotably mounted on the base. The switch contacts receive conductors which pass externally of the base for connection to an external circuit.

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.
