SPST Mini Toggle Switch ON-OFF
2Pin 2Position Simple On/Off Switch
This mini toggle switch is a Single Pole Single Throw (SPST) ON-OFF switch, featuring 2 pins and 2 positions. It is designed for simple circuit control, connecting or disconnecting a single power line in a wide variety of applications [citation:10].
Simple and Reliable Basic mechanism for making or breaking a circuit in lowvoltage projects
Compact Size - Versatile component suitable for panel mounting in tight spaces
Common current ratings: 6A at 250V AC or 10A at 125V AC [citation:1][citation:2]. 12V DC versions with ratings up to 20A are also common [citation:3].
The switch functions as a latching mechanism; flipping the toggle connects the two pins, flipping it back disconnects them [citation:4][citation:5][citation:6].
Use as a power switch to turn devices on and off, or as an isolator to completely disconnect a circuit.

Wiring Guide
For basic wiring, connect the power source to one terminal and the device/load to the other [citation:8]. This simple connection allows the switch to make or break the circuit.
Disconnect power before installation to prevent short circuits.
Use a multimeter in continuity mode to test the connection before finalizing the wiring [citation:6].
Troubleshooting
Switch not functioning:
- Verify the correct voltage and current rating for the application
- Check for a proper electrical connection (e.g., soldering, crimping) on both terminals
- Test the switch for continuity using a multimeter
