1) If you already have a It should be noted that the two wires on this old switch are not actually positive and negative. One is the +12 volt power from the battery, and the other is You can probably see that each of the two coloured wires is connected to one white wire and those two white wires are connected together inside the wall. The white wires pictured above are the negative, and the place in the new dimmer switch where the negative (neutral) wire will be connected. If you are using a volt meter or test light, determine which of the coloured wires is live after you have disconnected the old switch. The one coming from the battery will be that. The +12 volt side of the new dimmer should be connected to this. To the load side of the dimmer, connect the other coloured wire. B) If wiring is not already available, install a light since there is no existing switch To connect the positive wire of the light to the +12v wire of the dimmer, disconnect the positive wire from the light. The negative wire of the dimmer will need to be hooked up to the negative wire of the fixture. To connect the load wire of the dimmer to the open positive wire of the light, follow the guide below.
An example of PWM dimmers is shown below. I use led's for work and they work great
It is possible that your question could mean a number of In many cases, people connect the "negative" or "return" wire to ground, although this is inherently bad practice. For sure, you have to use the return wire or else the circuit is incomplete. It is likely that this building will have a lot more fires in the future since it lacks an independent ground.

Dimmers with a high side are known as high side dimmers. It's in the main living area of my fifth wheel, the Open Range. A total of six recessed 4W LED ceiling lights can be controlled by this controller. Initially, I feared installation would be difficult, but it turned out to be very simple. The voltage I measured was measured with a voltmeter instead. The circuit breaker box's cover has been removed and I discovered that all wires connected to the negative side (ground) are solid WHITE and all wires connected to the hot side are STRIPEY WHITE/RED. In essence, the WHITE/RED STRIPE is connected to the back of the existing on/off switch by the two wires on its ground pin. There are two wires on the switch. If you remove them from the switch, one wire will come from the breaker box (which supplies power), and the other will connect In this case, the voltmeter will be of use. It is imperative that you determine which of the two wires on the circuit breaker box comes from it. The red wire on the new dimmer will be your hot wire. Connect it to that. The WHITE wire from your dimmable switch should be connected to the other white/red wire that you removed from the original on/off switch (which should be connected to the light). In order to connect your dimmer, you'll find the white wire that is the negative (ground) wire that runs next to the white/red stripe wire, and connect that to the BLACK wire. There is a 3 wire dimmer connected to what was actually a 2 wire switch. In reality, the white/red stripe and the white wire are one single wire (2 separate wires bundled together), but they are separated for It was a good thing that the white negative/ground wire had already been cut and was joined together in a wire nut when I found it. My method of using the voltmeter was to place the BLACK lead into the wire nut with the spliced white wires and the RED lead of the voltmeter to each of the white/red stripe wires and see which one reads 12-volts. If you connect it to the lights, you will not get any illumination. The above procedure is for dummies when wiring a 12 volt dimmer. If you go digging around in the circuit breaker box in the RV, you should turn off the circuit breaker at the pedestal if you go digging around in the wires. In the pic above of the breaker box, you can see that the wires are white/red striped.
is a very high quality dimmer for my LED lights and I do not experience any flickering like I do with my other inferior.
As a replacement for fluorescent fixtures in my trailer, I have made several 10 watt LED ceiling lamps. There is a great deal more light with half the current. A great dimmer, it not only flickers smooth but also provides a very low wattage It is possible to go from full bright to the lowest dim setting freely. Efforts were made to make installation instructions clear, and the quality of construction was Those who are wondering, high side implies power is controlled by the positive wire, whereas low side implies power is controlled by altering the return to ground from the ground wire. Since it is power efficient, I believe it relies on pulse width modulation (PWM) for dimming. When the LED is dimmed, its measured amperage draw is reduced. A dimmer adds virtually no additional current draw, which means virtually no additional resistance. As I mentioned before I will be purchasing another one for my trailer to use for the outside LED lighting. I am very happy with the.
My camper awning had an LED strip installed that had to be dimmed. I found this to work well, it was easy to install, and I am not glowing in the dark under my canopy now! This is a HIGH SIDE PMW (Pulse Width Modulation) dimmer, which means it switches the 12 volt direct current that goes to the light. In order for this to work, a neutral must be present. The original switch had just two wires linked to it a +12vdc supply going into the switch, and a +12vdc supply going To connect the wires, I connected the RED wire to the +12vdc input of the old switch because it provided constant power, and I connected the WHITE wire to the +12vdc output of the old switch because it provided power In the next step, I connected the BLACK wire to a group of neutrals Thanks to this new feature, I can dim the awning leds now!.
The LED retrofit I have worked perfectly with this high side dimmer. With LEDs, older dimmers will not work as well as they do with traditional RV lamps. It works flawlessly and I am now able to brighten my LEDs in the bedroom as well. Whether or not you have an old-fashioned inline dimmer, you'll need to find some ground to tap into inside the wall. Low-side dimmers are more common on Amazon than high-side dimmers. These are types of dimmers that come in two different variations high and low. Sides with a high temperature During +12 volt feed stage, the switch is connected to the circuit before the load is connected. A low side is expected Depending on the type of load, the switch may be wired up after this. A return circuit consists of pin 12 and pin 13. You must get the right type of Most likely, if your RV came equipped with incandescent bulbs, this is the dimmer you need for the lights.
My foolish mistake of not testing it prior to wasting my last heat shrink connectors didn't work. As a result of thorough testing with a meter, I overcame my desire to hammer it (I have anger issues), and I disassembled the device. I am so impressed! As a result of the switch being installed upside down, the (offset) blades on the back of the rocker switch did not connect to the board socket. How'd I like not to have smashed Added a switch, uninstalled it, and then re-installed it. However, I was simply not able to get the circuit board to work, so I contemplated bypassing the dimmer function and using just the rocker switch, but to do so I would have had to leave the circuit board out, which would have been useless otherwise.
