Push Button Momentary Switch, SPST w/Rubber Cover, Weatherproof
A push button momentary switch is a type of switch that completes a circuit only when the button is physically pressed. When the button is released, the circuit is broken. Momentary switches are often used in applications where the user needs to control a device for a short period of time, such as a doorbell or a garage door opener.
Momentary switches are typically made of plastic or metal and may be flat-surfaced or contoured to the finger or hand. They have two terminals, one for the incoming current and one for the outgoing current. When the button is pressed, the two terminals are connected, completing the circuit. When the button is released, the two terminals are disconnected, breaking the circuit.
Momentary switches are available in a variety of sizes and shapes to suit different applications.
