Problems solved by technology

[0003] However, since the moving contact and the static contact often collide, there is a risk of breaking the moving contact as the number of collisions increases. Once the moving contact breaks, the switch will not be able to control the working circuit, resulting in a loss of control of the working circuit

Abstract

The invention discloses a change-over switch and belongs to the field of electric control. The change-over switch comprises a control module and a switching module, wherein the control module comprises a mounting seat, a supporting rod, a lever, an elastic part, an electromagnet and a first armature; the switching module comprises an insulating rod, a second armature, a first touch arm, a second touch arm, a first container and a second container; the second armature is fixedly connected with the lever through the insulating rod; the first touch arm and the second touch arm are electrically connected with the second armature; electrolyte is arranged in the first container and the second container; a top opening of the first container is distributed toward the first touch arm and a top opening of the second container is distributed toward the second touch arm; contacts for electrically connecting a working circuit are arranged at the bottom ends of the first container and the second container; when the first armature and the electromagnet are adsorbed together, the first touch arm is in contact with the electrolyte in the first container and the second touch arm is in contact with the electrolyte in the second container. According to the invention, the reliability of the change-over switch is improved.

Description

technical field [0001] The invention belongs to the field of electrical control, in particular to a changeover switch. Background technique [0002] The switch is a common electrical control element, which is used to control the on and off of the working circuit (large current). A common switch mainly includes a control module and a switch module. The control module is used to connect with the control circuit (small current). When the control circuit is connected to the control module, the electromagnet in the control module attracts the armature so that the armature drives the The moving contact and the static contact collide together so that the working circuit is connected. [0003] However, since the moving contact and the static contact often collide, there is a risk of breaking the moving contact as the number of collisions increases. Once the moving contact breaks, the switch will not be able to control the working circuit, resulting in a loss of control of the worki...
