Rotary Switches

212-3T2 Application Field and Working Principle

A rotary switch is a type of switch where the contacts are separated by a rotating knob or lever which can be moved to one of a number of different positions. The 212-3T2 is a rotary switch specifically used in low voltage and current applications, and is the most popular type of rotary switch available. The 212-3T2 is suitable for switching low voltage and current circuits, and it is designed to reduce the costs associated with wiring connections.The 212-3T2 rotary switch is primarily used in fan control, motor control, and light dimmers. It can be used to switch between several different operations or power levels of the same device, or to switch between different devices. The 212-3T2 rotary switch can also be used in many household electronic items, such as washing machines and vacuum cleaners.The 212-3T2 rotary switch consists of a cylindrical knob or lever, along with four sets of eight contacts. Each set of eight contacts has a central axis which rotates when the knob or lever is turned. This central axis is connected to the knob or lever, and when the knob or lever is turned, the contacts in each set of eight rotate, consequently changing the electrical connections.The contacts of the 212-3T2 rotary switch can be directly connected to the electrical wiring of the device in which the switch is installed. Alternatively, the contacts can be indirectly connected to the device’s wiring, by using electrical relays or circuit switches. The 212-3T2 rotary switch is designed to be used in low voltage and current applications, and offers a degree of protection from static electricity and other phenomena.The 212-3T2 is one of the most widely used rotary switches available, and its use is growing. Its durability, low cost, and ease of installation make it a great choice for both commercial and residential applications. The 212-3T2 rotary switch is a widely used switch which can be used to switch between different operations or circuit levels, and can be used in many domestic items, such as washing machines and vacuum cleaners. Its ability to reduce wiring costs and its reliability make it an ideal choice for a wide range of applications.
