There are usually 1 or 2 moving contacts in a switch.
1. Definition of moving contacts in a switch
The Movable Contact Rivet of a switch refers to the movable part inside the switch that is used to connect and disconnect the circuit. When using a switch, the moving contact plays an extremely important role and controls the on and off of the current. A switch generally consists of two parts: a static contact and a moving contact. When the switch is turned on, the moving contact is separated from the static contact; when the switch is closed, the moving contact is in contact with the static contact.
2. Types of moving contacts in a switch
According to the number of moving contacts, the moving contacts of a switch can be divided into two types: single contact and double contact.
1. Solid Silver Contacts: A single contact switch refers to a switch with only one moving contact. Due to its simple structure and low manufacturing cost, it is widely used in household appliances and some light-load appliances.
2. Bimetal Silver Contacts: A double contact switch refers to a switch with two moving contacts. This switch can control two appliances at the same time or switch circuits as needed. The price of a double-contact switch is generally higher than that of a single-contact switch and is suitable for occasions where more precise control is required in the circuit.
3. Use of switch-moving contacts
Moving Silver Contacts are widely used in electrical systems, especially in the home and industrial fields. All switches in the home, such as wall light switches, socket switches, electric fan switches, etc., use moving contacts. In the industrial field, switch-moving contacts are also needed in the control systems of various large electrical equipment. The design and use of switch-moving contacts are very important, and they can affect the performance and safety of the entire electrical system.
Conclusion
Movable Contact Rivets are the core components of the switch, and their number is generally 1 or 2. Pure Silver Contacts are suitable for household appliances and light-load appliances. Bimetal Contact Rivets are suitable for circuits that require more precise control. Whether in the home or industrial field, switch-moving contacts have a wide range of applications.
