embossed prototype metal dome tactile waterproof membrane switch

custom embossed prototype metal dome tactile waterproof membrane switch

Basic Parameter for the Membrane Switch

         Membrane switch is Compositive switch made of metal insulating material layers and conductive layers. It be   comes  the  first choice for the electric control switch for its unique Superiority. Good appearance, small volum, long life-span  and Bend resistance make the membrane switch popularly accepted. Also, it has strong resistances against the water, fire, oil and scratch. Hereby, the basic parameters of it is presented as follows:
