Mini LED Dimmer Knob - Control up to 4.8 amps @ 12V - Customer Questions

Frequently Asked Questions by Oznium Customers

Is it possible to wire 2 of these in an rv to control the same lights from either end of the rv?
Yes. You would need to extend the red and black wires from both switches. Wire both the black wires from both switches together and wire that to the ground on your power source. Then wire both red wires together and wire that to the positive on your power source. Then wire the white wire from the switch to the ground wire of the light. And the positive wire from the light to the red wires for the switch.
I am running two of these dimmers to two sets of lights . . When they share a common neg and positive the LED lights on one string flicker when dimmed . . .
Depending on which lights you are using it should be wired like this: Red wires from switch and leds to hot power source.
Black wires from switch to negative power source.
White wire from switch to one led ground wire, the other white wire from switch to other led black wire. If you are using a light that has a built in driver that might cause the flickering.
I have a strand of two-color leds (white and red). The are actuated by a three position rocker switch (on-off-on). Would it be possible to install this dimmer between the battery and the 3-position switch to dim both colors (dependent on the position of the 3-way switch)?
That should work but I would need to test that to make sure.
Placed a 5 amp fuse in my 12 v. led light strip, is that too much ?
A 2-3 amp fuse would be sufficient.
Will this dimmer also work with small incandescent bulbs? I bought it for use with custom car gauges that I thought would have LED's but came with incandescent bulbs. How might it be wired to work with the incandescent bulbs?
Let me check into this further and get back to you.
I want to use a rocker switch from the battery before connecting the dimmer to a LED strip so I can turn it off completely- how should I do this?
Not sure why you would need the rocker switch. The dimmer is an off/on switch also. Best to use that and connect to battery, then wire the dimmer to the strip. If you have more questions please contact Customer Support at 800-245-8131.
Hi how do I connect the red wire to both the power source and the LED?
You can connect 3 wires the same way you'd connect 2 wires. You could simply twist the 3 wires together and cover them with electrical tape or heat-shrink tubing. You could also solder them together. Or you could use a quick splice connector such as these.
I just tried installing one and it never worked for me. However I did short it, saw a little spark, and blew a 20 amp fuse when it happened. Should work now following the wiring diagram but nothing.
Sorry you are having problems. Please call customer service at 800-245-8131 for assistance.
Does this draw residual current when in the off position?
No. When the knob is turned all the way to the left, it "clicks" off, and zero current is drawn.
Does it work with 12 volts landscaping transformer?
Only if the transformer is 12V DC and not AC.
Does it work with 12 volt AC?
It only works with 12VDC to 24VDC. It doesn't work with AC.
Can this switch be wired in a "high side" fashion?
Sorry, no. It can only switch from the low or negative side.
What is the maximum voltage that your mini LED Dimmer Knob can withstand?

I have a 7S Lithium battery system in my RV. The max voltage (while charging) could be 30V. Will your dimmer work with voltage this high?
Our mini LED Dimmer Knob is designed to work with input voltages between 12VDC to 24VDC.
Sorry, it won't work on 30VDC. We suggest you use a DC-DC step down converter to make sure the voltage is no more than 24V.
