Abstract

An acceleration switch has a seismic mass, which is suspended by springs (1) on a bearing block (7). The springs are designed as curved bending springs. If an acceleration acts on this sensor, then the seismic mass is noticeably deflected out of its neutral position when a critical acceleration is exceeded. By means of a lever (17), the seismic mass pulls a contact bar (21) toward a contact block (4), so that a current path is closed between the two parts of the contact block (4).
