Switch

Abstract

The invention provides a switch which comprises a fixed magnet and a movable magnet, wherein the movable magnet and the fixed magnet can be positioned under the action of magnetic force. Operation hand feeling is embodied by the aid of the magnetic force between the movable magnet and the fixed magnet of the switch, and a contact operation mode of a traditional touch switch is replaced. As the movable magnet and the fixed magnet are in non-contact induction, mutual abrasion of parts is avoided, the operation handle feeling of operators cannot be affectedin long-time repeated use, and operation comfort is further improved.

Description

technical field [0001] The present invention relates to the technical field of electrical equipment, and more specifically, to a switch. Background technique [0002] At present, most of the switches installed in the circuit on the market are rotary or push-type. Among them, the rotary switches include car power window switches, electronic handbrake switches, etc.; the push-type switches include car steering wheel audio switches, air-conditioning adjustment switches, etc. [0003] Such as figure 1 As shown, it is a schematic structural diagram of a rotary switch, which includes a rotary body 01, a fixed body 02, an elastic component 03, and a friction component 04 (steel balls or plastic parts), wherein the rotary body 01 is manually operated The component rotates around the rotation center 05, and the rotation direction is shown by the arrow in the figure. The friction component 04 is arranged on the fixed body 02 through the elastic component 03, and is in contact with th...

Problems solved by technology

[0005] Among the above switches, whether it is a rotary switch or a push-type switch, they are all contact switches, that is, the human-operated parts need to be in contact with other parts to control the conduction and disconnection of the circuit. The contact parts of the rotary switch and the push switch will have a certain degree of wear or elastic fatigue, which will not only have a certain impact on their own life and the conduction effect of the circuit, but more importantly, it will greatly affect the operating feel.
