Medical Device Use 7 Keys Silk Screen Print Embossing Membrane Switch With King Bright LED
How do membrane switches work?
The design behind most membrane switches is simple: When an operator presses a button, a contact is made to activate an electrical circuit. When the operator releases the button, the contacts close to deactivate the circuit.
How are membrane switches made?
The design and manufacturing process behind the membrane switch is an e2ip technology with great care and creativity. Membrane switches are made by printing carbon or silver inks onto a variety of substrates. A custom graphic overlay is then applied to the film. At e2ip technologies we offer a wide range of graphics layer materials including polyester, antimicrobial polyester, polycarbonate, blends and silicone. These flexible, durable materials are where "membrane" switches get their name.
