The invention discloses an electronic sensing switching circuit which is used for sensing a stroke or a position of a linked switch and comprises a separation circuit, a sensing circuit, a sensing-circuit control circuit and a switching circuit. The separation circuit is adopted to receive a PWM pulse signal provided by a control guide circuit, rectifies and filters a positive phase PWM pulse anda negative phase PWM pulse of the PWM pulse signal to generate a positive phase direct current voltage and a negative phase direct current voltage and respectively provides the positive phase direct current voltage and the negative phase direct current voltage to the switching circuit and the sensing circuit for using as working voltages. In order to reduce energy consumption, by the sensing-circuit control circuit, the sensing circuit is controlled to be intermittently in a working state and detect motion of a magnet on the linked circuit in the working state to generate a position sensing signal to send to the switching circuit, and the switching circuit receives the position sensing signal to determine whether the linked switch is in a turn-off state or a turn-on state; the circuit is ingenious in structure; and when a power supply line does not need to be additionally added to supply power to the sensing circuit and the switching circuit, normal working of the control guide circuitis not affected.
Description
technical field [0001] The invention relates to a switch device, in particular to a switch device for car charging. Background technique [0002] In response to the requirements of energy conservation and environmental protection, electric vehicles are increasingly used in production and life. Electric vehicles use batteries as their power source. Therefore, electric vehicles need to be charged every certain use time. Generally speaking, electric vehicles use charging guns for charging. The switch is an important part of the charging gun. The switches used in the prior art for charging automobiles are often mechanical switches, which can be switched on and off through direct contact. This method has disadvantages such as limited life and low precision. Contents of the invention [0003] One of the purposes of the present invention is to overcome the deficiencies in the prior art and provide a power supply and working circuit of an electromagnetic switch for automobile ...
