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:
