The materials used for the graphic overlay exhibit a relatively high dielectric strength and volume resistivity. In cases where enhanced electrical shielding is required, the construction of a membrane switch can incorporate a higher degree of shielding. The specific requirements for shielding can vary significantly depending on the industry for which the product is designed. Shields can be designed to address the following:
- ESD (Electrostatic Discharge)
- EMI (Electromagnetic Interface)
- RFI (Radio Frequency Interface)
To introduce an additional shield beneath the graphic layer of the switch, conductive inks or metalized materials, such as aluminum-clad polyester, can be utilized. Grounding can be achieved through either a separate tail or by utilizing the same connector as the circuitry. Alternatively, a grounding tab can be created for connection to a metal backing plate or support panel.
Client Profile:
