Toggle switch with housing penetrated by switch extension

摘要

The switch has at least one moving contact part (20) bridging stationary contacts and containing two switching positions, i.e. ON and OFF. The moving contact part is prestress in one position direction and held in the other one by a permanent magnet (24). The permanent magnet field can be affected by the magnetic field of an electromagnet (25) such that the prestressed moving contact part can be moved to its other switching position when the electromagnet field has been built-up. Preferably the electromagnet is excited by a control pulse from a control electronic.
