Abstract

PURPOSE:To easily obtain a switch with a good contact adhesive property by using thermoplastic elastomer for a hollow mesa-shaped elastic body and thermoplastic elastomer added with a conductive materiel for a contact and integrally forming the elastic body and the contact. CONSTITUTION:A push button switch unit 1 is constituted of button switches 2, 2', 2''... and each has a hollow mesa-shaped elastic body 3 and a contact 4. The elastic body 3 is made of thermoplastic elastomer, the contact 4 is made of thermoplastic elastomer added with a conductive material such as carbon black, for example, and the push button switch unit 1 is integrally formed by the injection molding method or the like. When the contact 4 is to be formed by injection, a ring-shaped projection 4a is also formed, then the thermoplastic elastomer not added with the conductive material is injection-molded to mold the push button switch unit 1. A switch with a good contact adhesive property can be thereby obtained simply.
