Abstract (en)
[origin: EP0509368A2] A push-button switch is proposed having a plastic switch cap which acts as a restoring element, has a truncated-conical shape and makes possible a switching process which is highly precise in comparison with known rubber or silicon switch caps. In order to achieve an optimum switching characteristic, with defined switching movements and forces, a thermoplastic elastomer is used which, as a block-copolymer, has special characteristics with respect to the flexibility of the switch cap. In this case, the special characteristics of the push-button switch are determined by material selection and the dimensions of the switch cap. <IMAGE>
