Problems solved by technology

[0002] When we design an automatic control device, we need such a switch: it can be closed and kept closed by an external force. When other systems in the main road finish responding to the external force, the main road will be automatically disconnected, and this switch It should also be automatically disconnected and restored to the original state. The existing ordinary switches, spring switches, and electromagnet switches cannot take on this task.

Embodiment Construction

[0009] Below in conjunction with accompanying drawing, a kind of novel electromagnet switch of the present invention is described further.

[0010] A novel electromagnet switch comprises: a shrapnel, a contact, a spring, and an electromagnet.

[0011] When the shrapnel 1 is in contact with the contact 2 under the action of external force, the dry circuit is energized at the moment of contact, and the electromagnet 4 becomes magnetic, which instantly attracts the shrapnel 1 and maintains this closed state. After the other systems in the system have finished responding to the external force, they will automatically disconnect the main circuit, the electromagnet 4 will lose its magnetism, and the shrapnel 1 will automatically return to its original state under the elastic force of the spring 3. In order to "respond" to the next external force action, other systems in the main road are switched on again to receive the next external force "signal". Therefore, a kind of novel elect...

Abstract

The invention discloses a novel electromagnet switch which includes a spring splice, a spring, a contact and an electromagnet and belongs to the technical field of electromagnetism. In the technical scheme, in an instant moment when the spring splice contacts the contact under the application of an external force, a main circuit is switched on so that the electromagnet is magnified and absorbs the spring splice instantaneously and maintains the closing state. After other systems in the main circuit complete response to the external force, the main circuit is switched off and the electromagnet loses magnetism and automatically switches off under the application of the spring force of the spring slice and restores to an original state.

Description

technical field [0001] The invention belongs to the technical field of electromagnetism, and specifically relates to a novel electromagnet switch. Background technique [0002] When we design an automatic control device, we need such a switch: it can be closed and kept closed by an external force. When other systems in the main road finish responding to the external force, the main road will be automatically disconnected, and this switch Also should disconnect automatically, return to original state, and existing common switch, spring switch, electromagnet switch all can't take on this task. Contents of the invention [0003] In order to solve the above problems, the invention provides a novel electromagnet switch. [0004] In order to achieve the above object, the present invention adopts the following technical solutions: [0005] A new type of electromagnet switch, including a shrapnel, a spring, a contact, and an electromagnet. The shrapnel is connected to one pole o...
