摘要

The invention relates to electrical engineering and communications and may be used as a vibration-type controller, alarm, starting devices, etc. The technical result is to increase the reliability of the device due to application of the electronic circuit contactless switching device. The circuit is designed as a connected voltage divider, the electronic key and the inductive sensor, the first input of the inductive sensor is connected through diode D1 to the first terminal of the power supply, the other input - to the collector of transistor T3, which through the transistor emitter connected to the second terminal of the power supply, and, induction sensor being connected three-core cable to an electronic circuit, and the base of transistor T3 is connected to the emitter of T2 trigger, which, through its collector and base connected to a resistance of the trigger T1 which Comm inena the first and second power supply terminal.
