Abstract

Provided is a proximity switch device. A sensitive coil is connected with the input end of an oscillator through a wire. The output end of the oscillator is connected with a relay set through a triode amplifier. A magnetic field is formed at the end of the sensitive coil. According to the proximity switch device, the sensitive coil senses the magnetic field to generate electric energy, the electric energy is transmitted to the oscillator through the wire, the oscillator is connected with the relay set through the triode amplifier, and the switch is controlled to be opened or closed by switching on or switching off the relay. The whole proximity switch device is simple and firm in structure, high in reliability, not prone to damage and long in service life.

Description

technical field [0001] The invention relates to the field of electrical control equipment, in particular to a switch device. Background technique [0002] There are more and more types of switches used in the field of electrical control. Traditional spring switch devices usually have complex structures, poor opening and closing effects, easy damage, short service life, and low reliability, which brings inconvenience to use and maintenance.
