Mini PCB Slide Switch SPDT 3-Pin — G5 (5mm) / G6 (6mm) Shaft, 2-Position Toggle

Measure the depth of the mounting panel or enclosure wall where the switch will sit. If the panel is thinner, the G5 (5mm / ≈3/16") shaft typically provides a flush or slightly proud fit. For thicker panels or enclosures, the G6 (6mm / ≈1/4") shaft generally gives better grip and actuation clearance. When in doubt, check your PCB footprint or enclosure datasheet for the recommended actuator travel length.

Micro PCB slide switches of this type are generally rated for low-signal applications — typically 0.3A to 0.5A at 6V DC to 12V DC. They are not designed for mains or high-current loads. Always verify the rating against your circuit requirements before use, and contact us if you need confirmed datasheet values.

This is a standard open-frame PCB slide switch and is not sealed or rated for outdoor or high-humidity use. For moisture-prone environments, consider a conformal-coated PCB assembly or a sealed switch variant. Indoor electronics projects and dry enclosures are the intended use case.

SPDT stands for Single Pole Double Throw. The switch has one common (COM) pin and two output pins. In position 1, COM connects to output A; in position 2, COM connects to output B. This makes it ideal for routing a signal between two circuits or toggling between two operating modes — for example, switching between two sensor inputs on a microcontroller board.

Micro PCB slide switches in this form factor generally use a 2.54mm (0.1") pin pitch, which is compatible with standard through-hole PCB layouts. Confirm the exact footprint dimensions against your PCB design files before soldering, as minor variations exist between manufacturers. A breadboard test fit before final assembly is always a good practice.

For prototyping or one-off builds, the 1-piece or 2-piece option lets you validate fit and function without committing to bulk. For small production runs or repair kits, the 5-piece or 10-piece packs offer a lower per-unit cost and ensure you have spares on hand. All pack sizes ship from our US warehouse.

Yes, SPDT slide switches are commonly used in DIY audio electronics — for example, toggling between pickup modes on guitars, switching EQ bypass, or selecting signal paths on effects pedals. The low-profile PCB mount design keeps builds compact. Ensure the switch's contact resistance is acceptable for your signal level, and test with your specific circuit before finalizing the design.
