Waterproof Solution

Many applications require waterproof for the membrane switches. ElecFlex provides the following solutions
1. Frame seal gasket
A frame seal gasket without any gap will be installed at the perimeter of the circuits. That will protect the circuits and tail from humidity and considerably lengthen the life of the membrane switch which is used in the environment with high humidity.
2. Rigid PCB / flexible PCB based circuits
Replacing the regular silver paste based circuits with a rigid PCB or a flexible PCB, plus strong internal spacer, will make your membrane switch very durable in a wet environment. Typical application is outdoor use.
