0.175mm Matte PC overlay material embossing button membrane switch with 3M467 adhesive

Product Overview

Description

0.175mm Matte PC overlay material embossing button membrane switch with 3M467 adhesive

 

Emboss button membrane switch keypads have a snap action that is clearly noticeable to the operator. Conductive stainless steel snap domes have the best action. They can also eliminate the need for a flexible upper circuit layer. To ease the final mating of the switch and avoid the possibility of a dome becoming inverted a .015" - .020" backing layer can be provided.

Membrane switch panels technical information:

	1. Graphic Overlay	PC or PET( Polyester is usually the material of choice due to its superior chemical resistance and flex life compared to polycarbonate.) Glossy surface or matte surface
	2. Overlay Adhesive	This adhesive layer bonds the graphic overlay to the top circuit layer, and is typically an acrylic adhesive.
	3. Top Circuit Layer	0.005" - 0.007" heat stabilized polyester printed with silver-filled electrically conductive inks and also dielectric inks.
	4. Circuit Spacer	This layer separates the top circuit from the bottom circuit so the switch remains normally open until the keypad is pressed. The circuit spacer is a polyester spacer with adhesive on both sides.
	5. Lower Circuit Layer	0.005" - 0.007" heat stabilized polyester printed with silver-filled electrically conductive inks and also dielectric inks. This layer terminates as a flexible tail that serves as the interconnect to controller PCBs or other electronics.
	6. Read Adhesive Layer	This adhesive layer bonds the entire membrane switch package to the product enclosure, housing, or to a rigid support panel.
	7. Rigid Support Layer	This optional layer can add structural integrity to the membrane switch assembly.

 

Membrane switch panels can be built with non-tactile switches, which activate with 4 – 8 oz of touch pressure. Non-tactile switches are less expensive and provide the longest switch life. Tactile switches have a snap-action feel and may also be incorporated into a membrane switch, enhancing tactile feedback, but with a greater cost and lower switch life.
