Microswitch used in electronic devices comprises flat substrate, spring having a fixed and a free section, and a device for pressing the spring onto the substrate

摘要

Microswitch comprises a flat substrate (1), a spring (2) having a fixed (3) and a free section (4), and a device for pressing the spring onto the substrate. Microswitch comprises a flat substrate (1), a spring (2) having a fixed (3) and a free section (4), and a device for pressing the spring onto the substrate. A fixed contact (10) is arranged on the surface of the substrate. The fixed section of the spring is connected to the substrate and the free section is bent in its open state on its end facing the fixed section away from the substrate. The free section has an end section (11) for a moving contact (9) which interacts with the fixed contact. The outer surface of the moving contact protrudes from the end section so that the moving contact touches the fixed contact in the closed state. The end section is arranged at a distance d from the substrate and/or the fixed contact. An Independent claim is also included for a process for the production of the microswitch. Preferred Features: The distance d is at least 10 microns m. A sacrificial layer is produced between the fixed contact and the moving contact by etching.
