Detail Information
Description :
A membrane switch consists of two polyester films screen printed with conductive ink to complete the circuit. A spacer in between two circuits, which is, die cut at contact points. The die-cut holes allow the touch of a finger to close the contact, completing the circuit. The circuit is broken when released. The panel posterior is laminated with an adhesive for mounting to a backer or enclosure and is terminated with a means for interfacing with the customer’s electronics.
This particular sample is a combination of membrane switch + silicon rubber, where Elcom has developed and manufacture such technology ahead of such product market becoming a trend in membrane switch keypad making industry.
