This Narva Off/Momentary (On) Toggle Switch runs a simple SPST circuit at 20A on 12V or 10A on 24V, so you can run light loads or trigger a relay without drama. The action is Off in one position then momentary On when you hold the lever, which works well for horn circuits or test lamps. The body drops into a 12mm panel hole, handy for crowded dashes and accessory pods.

The switch housing uses a solid metal threaded bush with a nut that clamps firmly onto panels around 1–3mm thick. Standard push-on blade terminals mean your usual 6.3mm crimp lugs slide straight on, which keeps repairs simple on the road. The Narva rating of 20A at 12V is well matched to typical accessory wiring sizes found in Aussie 4WD and trailer setups, so you get gear that behaves as expected when heat and dust turn up.

Q: Is this switch latching or momentary?

This switch is Off in the rest position and momentary On when the lever is held. Once you release the lever it springs back to Off. That makes it handy for horn circuits, test lamps, or any gear you only want powered while you hold the switch. It is not suitable where you need a constant On without holding the lever.

Q: Can I use this switch to drive a relay coil?

Yes, the 20A rating at 12V easily covers the low current draw of a typical relay coil. Using it to trigger a relay is a good way to control higher current loads. Keep the relay close to the battery and load, then run a lighter-gauge trigger wire back to the switch. This keeps voltage drop down and wiring tidier across the vehicle.

Q: What connector type fits the push-on terminals?

The switch uses standard push-on blade terminals that suit common automotive female crimp connectors. Matching insulated crimp lugs give the best grip and reduce the chance of short circuits. Always check the lug width against the terminal before crimping. A firm slide-on fit means the connection will stay put on corrugated tracks.

Q: Will this fit in a thin metal or plastic dash panel?

The threaded bush and nut design suits typical thin dash or bracket panels. A clean 12mm round hole is all that is required for mounting. Tightening the nut locks the switch body firmly without extra brackets. Using a flat washer under the nut can help spread the load on softer plastic surfaces.
