Product Description
A membrane switch is a momentary electrical contact on/off switch that activates or deactivates an electric circuit. These single pole, single throw, normally open (SPSTNO) switches are manufactured by screen printing circuits directly onto plastic substrates with silver or carbon conductive ink. The simple, versatile, durable, and economical design makes membrane switches a superior alternative to mechanical switches.
