Problems solved by technology

[0002] The magnetic switch in the prior art is an electromagnetic switch, such as an electromagnetic lock. When the power is turned on, the electromagnet generates electromagnetic force to attract and close the locked object. This solution needs to consume electric energy all the time in the working range of the switch, and basically It converts alternating current into direct current to control the operation of electromagnet, that is, this kind of scheme adopts strong electric connection, which has unsafe problems

Abstract

The invention discloses a weak electromagnetic force switch, which comprises a fixed part, a movable part, an elastic assembly and an electromagnetic assembly. The movable part and the fixed part arein magnetic attraction connection through a permanent magnetic assembly. The elastic assembly is connected between the fixed part and the movable part in a compressed mode. The electromagnetic assembly is used for generating magnetic force repelling the magnetic force of the movable part and the fixed part when being electrified so as to release the magnetic attraction state of the movable part and the fixed part. When the magnetic attraction state of the movable part and the fixed part is released, thrust generated by elastic extension of the elastic assembly acts on the movable part. The weak current electromagnetic switch not only can be used as a safe and power-saving magnetic switch, but also can be used as a large power driver.

Description

technical field [0001] The invention relates to the technical field of well covers, in particular to a weak electromagnetic force switch. Background technique [0002] The magnetic switch in the prior art is an electromagnetic switch, such as an electromagnetic lock. When the power is turned on, the electromagnet generates electromagnetic force to attract and close the locked object. This solution needs to consume electric energy all the time in the working range of the switch, and basically It is to control the operation of the electromagnet after converting the alternating current into direct current, that is to say, this kind of scheme adopts strong electric connection, which has the problem of unsafety. Contents of the invention [0003] The main purpose of the present invention is to provide a safe and power-saving weak electromagnetic force switch, which can be used as a high-power driver. [0004] In order to achieve the above object, the weak electromagnetic force...
