4mm SPDT 1P2T Slide Switch (Pack of 10)

A 4mm SPDT 1P2T slide switch is a type of switch commonly used in various DIY projects and small electronics. Let me break down what each of those specifications means:

1. 4mm: This likely refers to the size of the switch, specifically the width of the slider or the overall dimensions of the switch body.
2. SPDT: This stands for Single Pole, Double Throw. It means that there is one input (pole) and two possible outputs (throws). In other words, it can connect the input to one of two output terminals.
3. 1P2T: This further specifies the configuration of the switch. “1P” means one pole, indicating that there’s one input connection. “2T” means two throws, indicating that there are two possible output connections.
4. Slide Switch: This indicates the type of switch mechanism. A slide switch is operated by sliding a lever or button from one position to another to change the state of the switch.

These switches are commonly used in electronics projects where you need to manually switch between two different circuits or states, such as turning a device on or off, selecting between different modes, or choosing between different signal paths. They’re popular due to their simplicity, compact size, and ease of use.
