A high security electronic switch

Abstract

The invention belongs to the electronic switch field and especially relates to a high-safety electronic switch. The switch comprises a shell, an electromagnet and a power supply. One side of the shell, which is close to the power supply, is provided with an installation groove. The installation groove is provided with a switch key block. A top of the electromagnet is provided with a permanent magnet. The permanent magnet can move upwardly under a magnetic force effect of the electromagnet. A slide bar is fixedly connected to an upper portion of the permanent magnet. A side surface of the slide bar, which corresponds to the shell, and a side surface of a separation plate are provided with chutes. One end of the slide bar, which is close to the side surface of the shell, is provided with a third contact point. A tail end of the third contact point, which is along a chute motion direction, is provided with a fourth contact point. The fourth contact point is connected to a first connector lug arranged on an outer side surface of the shell. The third contact point is connected to a second connector lug arranged on the outer side surface of the shell. By using the electronic switch, isolation of operation personnel and a high voltage switch is effectively guaranteed, the structure of the switch is simple and the electronic switch is economical and practical.

Description

【Technical field】 [0001] The invention relates to the field of electronic switches, in particular to a high-safety electronic switch. 【Background technique】 [0002] In a circuit that requires frequent on-off, such as high voltage, such as 380V, it is very unsafe to use an ordinary switch as an on-off device. On the one hand, at the moment of switch on-off, due to the The air gap is very small, so the air is easily punctured by the voltage, thereby generating an arc and causing an electric accident. On the other hand, when the ordinary switch is on and off the circuit, the current in the circuit often increases instantaneously, that is, the current impact of the circuit is very strong. , which has a greater impact on power equipment and shortens the life of power equipment. [0003] Therefore, in order to ensure the safety of the operator, it is very necessary to design a high-safety switch in view of the above situation. The operator controls the low-voltage switch to auto...
