Depending on the type of membrane switch design, the graphic overlay material or the molded rubber materials both have a relatively high dielectric strength and high volume resistivity. If required, a higher degree of electrical shielding can also be integrated into the membrane switch construction. The requirements can vary depending on the industry the product will be used in.
Shields can be designed for the following:
CSI utilizes three basic shielding methods to protect membrane switches:
