It is also called a magnetically controlled switch. Commonly used magnetic switches are single-contact and double-contact. A magnetic switch means sensing through a magnet. The "magnet" here refers to a magnet. There are several types of magnets. Commonly used magnets on the market include rubber magnets, permanent ferrites, sintered neodymium iron boron, etc. The switch is a reed switch, which is the abbreviation of a dry reed switch. It is a passive electronic switching element with contacts. It has the advantages of simple structure, small size and easy control.
