Mini Toggle Switch – 3A, 3-Pin SPDT

A Mini Toggle Switch – 3A, 3-Pin SPDT Single Pole Double Throw has three terminals: one common, one normally open, and one normally closed. Moving the lever connects the common terminal to either the normally open or normally closed pin depending on which position the lever sits in. That three-terminal layout makes the SPDT switch more flexible than a simple two-pin ON/OFF switch – the same switch routes one input signal to two different outputs, or selects between two input sources for one output, depending on how the 3 pin toggle switch is wired in the circuit.

The toggle mechanism latches in position flip the lever up and it stays up, flip it down and it stays down. That latching behaviour is the key difference from momentary push buttons, making it appropriate for power switches, mode selectors, and enable/disable controls where the switch state must remain fixed without the operator holding it. Rated at 3A, the spdt toggle switch handles standard low-voltage DC project wiring and light-duty panel switching loads.

The voltage rating is not specified in the supplied data confirm the maximum operating voltage with the supplier before using in high-voltage mains circuits, as the 3A current rating alone does not confirm mains suitability. The mini toggle switch compact body fits standard panel cutout holes in project boxes and enclosures. This toggle switch is available on StemVolt, its working on build control panel and electronics switching projects.
