SP3T switch is a circuit switch

A SP3T switch is a circuit switch that is switched on and off by turning the switch. It has four terminals. One is the primary point, and the other three are the dynamic points. The principle is to connect different circuits in the three positions of the switch, by rotating the switch, you can choose which circuit to connect. The structure of a SP3T switch includes a rotating shaft and a group of rotating contact rods. Each contact bar has three fixed contacts that contact different circuits at different angular positions. In addition, there is a set of spring contact plates on the body of the switch, which, when rotated, contact the contacts of the contact rod, thus connecting the current path to the different circuits.

SP3T switch is widely used in various types of circuits because of its simple and reliable characteristics, including but not limited to the following aspects:

1. Communication equipment: The SP3T switch is commonly used in wireless communication devices, such as mobile phones, wireless routers, etc. It can be used to switch the transmission path of signals, such as switching between different antennas or network frequency bands in mobile phones.
2. Automation system: The SP3T switch can be applied in automation systems to switch between different sensors or actuators. For example, in industrial automation, SP3T switches can be used to switch between different sensors to collect different data.
3. Laboratory and testing equipment: SP3T switches are also common in laboratories and testing equipment. It can be used to switch between different test signal sources, measuring instruments or equipment.
4. Audio and video devices: In audio and video devices, the SP3T switch can be used to switch between different audio or video input sources. For example, it can be used to select different audio or video sources.
5. Electronic equipment maintenance: The SP3T switch can also be used for electronic equipment maintenance and troubleshooting. During equipment maintenance, the SP3T switch can be used to switch between different circuit connection states to determine the problem or verify the repair effect.
