MEMBRANE KEYBOARD

Membrane switches are those elements of electronic systems, which are responsible for communication between users and devices. They consist of multiple layers of polyester films and silver conducive printed circuit board. The role of the NO contact is played by the incorporated polyester or metal dome.

 

Our membrane switches are ready for self-sticking on housings.
