Product Overview
The Mini Slide Switch 3-Pin from Pro Tronix is a fundamental component for adding a manual power toggle to miniature electronic devices. Featuring a smooth sliding actuator, it provides a clear mechanical “lock” into position, preventing accidental toggling. While it features 3 pins (SPDT), it is most commonly used for ON/OFF functionality by utilizing the center pin and one side pin. Its lightweight and slim design makes it the standard choice for wearable tech, small toys, and DIY handheld gadgets.
