Installation at a Glance
1
Drill a 12mm hole
Use a step drill or standard 12mm bit. Panel thickness up to ~6mm works well.
2
Fit the switch and plate
Insert the switch through the hole, place the ON/OFF panel plate, then secure with the locking washer and nut.
3
Connect your wiring
Use M3 crimp lugs or tinned bare wire on the screw terminals. Tighten firmly without over-torquing.
4
Fit the rubber boot
Slide the waterproof boot over the toggle for moisture and ingress protection.

Common Questions
What size hole do I need to drill?
12mm diameter. The switch uses an M12 thread with the included locking nut to secure it to the panel. Panel thickness up to ~6mm works well.
Can I use this to switch 12V DC (car, boat, van)?
Yes — this switch is rated at 30A @ 12V DC, making it well suited for high-current 12V automotive, marine, and van accessory circuits. For inductive loads like motors or compressors, consider using a relay for sustained high-current switching.
Does the boot cap affect the toggle feel?
Slightly — the rubber boot adds minor resistance to the toggle action. It's designed to keep moisture out of the switch body and does not affect electrical performance.
Please note: For mains AC applications, installation must be carried out by a licensed electrician in accordance with NZ wiring standards.
