APEM introduces standard, off-the-shelf, NEMA 4 membrane switches. They are a quick, low-cost solution for beta test prototypes or they can be designed into the final product. When customized membrane switches are needed Digi-Key works with APEM to design, develop and produce the customized keypad to fit the project’s specific needs.
A membrane switch is a multi-layered momentary switch consisting of a graphic overlay, top circuit and lower circuit. This switch type is used across all industries due to its flexibility to be customized, reliability and price point. Membrane switches are a proven technology. They are used in all industries such as military, medical, oil and gas, gaming, transportation, food & beverage, industrial, and more. Now Digi-Key offers APEM's off-the-shelf membrane keypads in rectangular 4-key, 8-key, 12-key, 16-key, and 4-key and 5-key oval configurations.
