ABSTRACT:
A bistable switch comprising an electrically and magnetically conductive flexible contact member clamped at one end, the other freely movable end being alternately brought into contact, by a magnetic excitation flux, with one of two electrically and magnetically conductive counter-contacts. After termination of the excitation flux, the contact position is maintained by a permanent magnet. The contact member comprises a strip-shaped portion having a high magnetic resistance which is comparatively flexible and a strip-shaped portion having a low magnetic resistance which is comparatively rigid. The magnetic as well as mechanical properties of such a switch can thus be optimized.
