摘要

The electronic circuit has two switching states equipped with a reed contact (S) in the presence of a switching magnet, where the reed contact acts as a closing contact. An inverter circuit is connected with the reed contact, which inverts the switching state of the reed contact. The reed contact bridges a base-emitter junction of a transistor (T1,T2) in the inverter circuit.
