Miniature 1P2T SPDT Slide Switch (Pack of 2) – 4mm Vertical PCB Mount Toggle for Small Electronics, Robotics Power, and Project Mode Selection

Product Description The 4mm SPDT Slide Switch is an ultra-small, three-pin mechanical switch designed for low-power signal or power toggling. Its Single Pole Double Throw (SPDT) configuration allows the user to switch a single input between two different output paths (1P2T). This switch is a favorite at Robogears Pvt Ltd for integrating master power controls into compact handheld devices, selecting between dual battery sources, or toggling between "Programming" and "Run" modes on custom controller boards. Its vertical 4mm handle is easy to manipulate while maintaining a low-profile footprint on the PCB.

Key Highlights

• Miniature Footprint: The extremely small body size is perfect for high-density PCBs and space-constrained enclosures where a standard rocker switch would be too large.

• SPDT Functionality: With 3 pins, you can use it as a simple ON-OFF switch (using 2 pins) or as a selector switch to flip between two different circuit branches.

• Stable Latching Action: The mechanical slide mechanism locks firmly into place at either end, preventing accidental state changes from vibrations or bumps.

• PCB Mount Design: Features standard through-hole pins that provide a strong mechanical bond once soldered, ensuring the switch can withstand frequent use.

• Low Contact Resistance: High-quality internal contacts ensure minimal signal loss, which is essential for low-voltage sensor circuits or battery-powered logic.
