A double pole rocker switch will have either 4 or 6 terminals on the back. A three terminal rocker will have a terminal to connect your source, and two terminals for the two loads the switch will operate. An illuminated rocker switch will have an extra terminal to connect either a ground wire or common wire to allow the indicator light to illuminate. An ON-OFF rocker switch will have a terminal to connect to your battery or source, and a second terminal to connect to your load or accessory. Connections on the back of the rocker switches is usually made using 1/4 inch push-on terminals. MOMENTARY operation means that when your finger is removed from the switch, the switch goes back to the OFF position. And finally, each switch function can be either ON, OFF, or MOMENTARY operation. A double pole rocker switch is basically two switches in one so that you can operate two circuits with a single switch. For each function, the switch can be either a single pole, or double pole switch. Rocker switches come in either two function, such as an ON-OFF switch, or three function such as an ON-OFF-ON switch. Because of how nice they look, the extra work involved can be worth it. Most rocker switches are designed to fit a rectangular cutout, which is much harder to achieve than simply drilling a hole. Some feature two linked toggles.Rocker switches provide a visually pleasing way to switch on and off your electrical circuits. They are used in settings where visibility and easy access are crucial - for example, aeroplane control panels. Large toggle switches are designed to provide on-off control. They are resistant to damage from electric surges or arcs. Microswitches are typically fitted in complex configurations. Industrial anemometers and control circuits For example, they can be used to ensure a door or hatch is shut before power is activated and to trigger a shutdown of the current when the door or latch is reopened. Principally designed for lower currents, microswitches are cheap and widely used in both domestic and industrial equipment, often as sensors to detect the position of a component for safety reasons. SPST Toggle switch (Singe Position, Single Throw) A SPST switch is a simple On Off switch. Improper wiring can damage your vehicle’s electrical system or cause a fire. The spring is energised by the inflow of current and this moves the contacts into place. If you have any doubts, go to a professional. They feature a sensitive spring-loaded toggle and respond to a small amount of applied force. These smaller toggle switches are also known as microswitches or snap action switches. on or off).Ī variety of matching accessories are available. LED toggle switches include a light-emitting diode (LED), typically in the tip of the toggle, which indicates the status of the switch (i.e. The term flat toggle switch may refer to switches with a flat-sided toggle, or switches in flat metal plates for vertical or horizontal fitting (for example on walls or the sides of machinery). They can protect the tips of the internal lever mechanism, prevent the switch from being activated accidentally or click the switch off when closed. These switches feature covers or caps which serve various functions. Other Toggle Switch Types Toggle Switch with Cover They are versatile devices and can be used with almost any electrical application. Toggle switches are also known as joystick switches and toggle power switches. They are similar in function to rocker switches, but the latter feature a see-saw shaped button that swings from one position to another and are sometimes classed as a type of rocker switch. Toggle switches are actuators - devices that switch a machine on or off. In each position, it will normally latch into place and remain there until moved back. Toggle switches feature a manually operated hinge, handle or lever mechanism - called a toggle - which moves from one position to another. Then when the contact is moved away again the flow of current is broken, the circuit becomes open and the device is switched off. When the contact is connected, the circuit is closed - live - electrical current can flow through and the attached device will turn on and operate. This is achieved by removing a metal contact from the terminal (endpoint of a circuit) or bringing the two back into contact. Electronic switches provide on-off control for electrical circuits by interrupting the flow of current or allowing it to resume.

Toggle switches are a type of electronic switch, one of the most basic and widely used electrical components.
