> Application 

Classic applications of membrane switches include consumer electronics like the microwave oven panel, air conditioner control panel, TV remote control etc., machinery, test instrument, meters, medical industry, energy industry, Auto industry, aviation industry, healthcare industry etc. Tactile feedback of keys can be provided by embossing the top PET/PC layer or embedding metal snap domes, polyester domes or forming the graphic layer.

The benefits of membrane switches include flexible, easy of cleaning, sealing ability and low profile.
