[0002] An electronic switch refers to an operating unit that uses electronic circuits and power electronic devices to realize the on and off of a circuit, and includes at least one controllable electronic driver, such as a thyristor, transistor, field effect transistor, thyristor, relay, etc. However, in actual use, electronic switches mainly refer to wall switches such as touch switches, induction switches, voice-activated switches, and wireless switches. In a broad sense, an electronic switch is a unit that uses electronic technology to drive a certain component through current or voltage to realize the on and off of a circuit. There are normally open, normally closed, self-locking, etc.

[0003] At present, conventional automotive electronic combination switch mechanisms use brushes to slide on circuit boards to achieve mechanical switch functions, which have high requirements for brushes and poor durability, and are prone to poor contact. Especially in dusty environments, dirt can more easily cause switch function failures. The current mechanism has a low safety level, so the existing technology needs to be improved.
