High Performance 3 Embossed Metal Dome Membrane Switch Keyboard

3 Embossed Metal Dome Membrane Switch with Over 1,000,000 Times Lifespan

Basic Parameter for the Membrane Switch

Membrane switch is composite switch made of metal?insulating material layers and conductive layers. It becomes?the?first?choice for the electric control switch for its unique superiority. good appearance, small volume, long life-span?and bend resistance make the membrane switch popularly accepted. Also, it has strong resistance against the water, fire, oil and scratch. Hereby, the basic parameters of it is presented as follows:
