FORIOT 15Pcs MTS-102 Mini Toggle Switch 6A 125V AC Toggle Switch 3-Pin 2-Position ON/ON Miniature Toggle Switch

The three pins of the MTS-102 toggle switch are as follows: 1. Common Pin (COM): this is the center pin and is used to connect common wires in external circuits or parts of circuits that are normally used. 2. A contact (Normally Open Pin, NO): This is the pin located on the side of the toggle switch that is disconnected from the common pin (COM) when the switch is not connected. When the toggle switch is toggled to position A, the A contact is connected to the common pin (COM), forming a path. 3. B Contact (Normally Closed Pin, NC): This is the pin located on the other side of the toggle switch and is connected to the common pin (COM) when the switch is not connected. When the toggle switch is toggled to the B position, the B contact is disconnected from the common pin (COM), cutting off the pathway. The principle of operation of the MTS-102 toggle switch is simple. With the toggle switch, you can switch the state of the circuit connection between the A position and the B position. When the toggle switch is toggled to the A position, the A contact is connected to the common pin (COM) and the B contact is disconnected. When the toggle switch is toggled to the B position, the B contact is connected to the common pin (COM) and the A contact is disconnected. In this way, you can switch between the two connection states. The MTS-102 toggle switch is widely used in electronic circuits, especially in small electronic devices, DIY projects and prototyping. For example, switching different signal sources in a circuit, controlling different function modules or selecting different operating modes. Due to its simplicity and reliability, it is one of the favorite components used by many electronic hobbyists and engineers.
