Electromagnetic transducer for converting energy for powering radio-controlled switch circuitry, has magnetic circuit which is opened or closed by movement of moving member from rest position

摘要

An electric coil encloses at least part of a permanent magnet (2) or moving member (6). A movement of the moving member out of a first rest position or a second rest position leads to an opening or a closing of the magnetic circuit. The moving member is made of a soft magnetic material, and may be formed as a spring member.
