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:
