Overview

Membrane Switch with Graphic
Overlay and Embedded LED’s

Other circuits primarily include Polymer Thick Film (PTF) flexible circuits, aka membrane switches such as graphic overlays, touch pads and key pads. The membrane switch functions as a normally open, momentary contact, low-voltage pressure-sensitive device. The design of a membrane switch starts with a polyester layer. Through a screen printing process, conductive patterns are deposited onto the polyester layer. Then a dielectric insulator is added to insulate the conductive patterns and leave openings where the conductive ink should remain for electrical contact.

When pressure is applied to the top layer, it flexes through the punched openings of the spacer to establish electrical contact between conductive pads of the upper and lower sheets, momentarily closing the circuit. When pressure is released from the top layer, it springs back to its normal open position.

We will take on any design challenge because we are leaders in technology & process development of membrane switch circuits. We will find a solution within our broad range of capabilities, including design, engineering, manufacturing, die-cutting and surface mount technology. We take pride in tackling the toughest design challenges related to PTF flex circuits.
