Poly dome Tactile Membrane Switch Product Description
1, Polydome, it is formed by hot pressing of polyester film line to make it have the function of switching. There are the following advantages
1.1 Can design the feeling of force, not the metal shrapnel is restricted by the material.
1.2 Low cost, more suitable for various types of PCB.
1.3 Does not damage the line and can reach the additional function of the protective line.
1.4 Prolong the service life of the product.
1.5 FORCE and the height of molding and relationship between the diameter of septal perforation
Polyester is an overlay of choice because it is more durable than switches with overlays made from other types of materials, such as polycarbonate. Polyester especially is a good choice if your application has more than 50,000 actuations; in fact, life cycle tests show that polyester may be actuated more than 1,000,000 times in a tactile switch without showing signs of wear. If you are looking for appropriate levels of tactile feedback in your membrane switch, make sure your overlay thickness is between .006 and .010.
