12V DC project power controls
Bench equipment and enclosure panels
Maintained ON/OFF control circuits

Wiring & getting started

  1. Check the panel fit

    Check the nominal 12.2mm hole against the supplied switch before drilling. Allow space behind the panel for the body, terminals and wire bends.

  2. Mount from behind the panel

    Remove the front retaining hardware, insert the threaded bushing from behind, then fit the plate and retaining hardware. Adjust the rear nut to suit the panel and fit the boot if required.

  3. Check the contact operation

    With power disconnected, measure continuity between the two screw terminals. ON closes the circuit and OFF opens it. Align the plate with the measured operation.

  4. Connect and protect the circuit

    For low-voltage DC use, wire the switch in series with the load and fit a suitable fuse near the supply. Secure and insulate the connections. Use a suitably rated relay for motors or other loads with high starting current. Apply each rating only with its stated voltage and AC/DC type.

Note: The boot covers the lever. Protect the body and terminals from water. Mains-powered equipment requires appropriate enclosure and insulation, with installation by a qualified electrician.

Frequently Asked Questions

Answers to the questions buyers ask most.

Does the lever stay on, or spring back?
It stays in the selected ON or OFF position. This is a maintained SPST switch with two terminals.
Can I use it on a 12V DC circuit?
Yes. The switch body is marked 30A at 12VDC. Match the switch to the load and its starting current, and use a suitable fuse. Use a suitably rated relay for motors or other high-starting-current loads.
What hole does it need in the panel?
The nominal mounting hole is 12.2mm for the M12 x 0.75 threaded bushing. Check the supplied switch before machining and allow room for mounting hardware and connections.
Does the rubber boot protect the whole switch?
The boot covers the lever. Install the body and screw terminals inside an enclosure that protects them from water.

Why Buy from NZN

Useful parts, fair prices and someone local to help.

I'm Lukas, an engineering student and maker based in Te Awamutu. NZN grew out of a CNC build that dragged on for months because every missing cable, bolt or electronic part meant another overseas order. I started the shop so Kiwi makers can spend more time building and less time waiting for the next parcel.
