摘要

The push-button has a metal spring snap disk (1) comprising an edge section (12), which makes an electrical interconnection to a contact element (2) in an unactuated position of the push-button. Snapping of the snap disk makes a pressure action on a central portion (11). A lower side of the central section makes an electrical interconnection to another contact element (3) that is arranged at a lower side of the central section and moves the edge section of the snap disk. The latter contact element is arranged in an operation direction of the push-button slidingly on a spring element (8). The former contact element is designed as an annular strip conductor on a carrier element (13). The spring element is designed as a curved spring strip or a dome-shaped spring body.
