Wiring & getting started
- Disconnect power
Do all continuity checks, mounting and soldering with the circuit de-energised.
- Find common
On this stock, the centre lug is common. Confirm it with a continuity meter before final wiring.
- Map both positions
Move the lever each way. Common should connect to one outer lug, then the other, with no centre-off position.
- Mount and connect
Use a 6mm nominal panel hole, secure the hardware without crushing the panel, then insulate the finished joints.
Note: One SPDT switch cannot reverse a two-wire DC motor because it cannot reverse both conductors. Use a DPDT switch or a suitable motor driver. Have mains wiring specified and completed by a licensed electrician.
