Quick Answer

Frequent Question Can you put a dimmer switch on 12 volt LED lights?


These drivers are “electronic low voltage” power sources, so they require a dimmer switch that has reverse phase control. Unlike switches used with our dimmable drivers, the 12V dimmer switches are connected between the driver (or adapter) and the light.

Can you use a 120v dimmer switch for 12V?

Yes, you can use a 120v switch for a 12v application. The 120v is the max voltage rating of the switch, which states that it can handle voltages up to 120 volts. If you will be using the 120v switch in a 12v application this will not be a problem, as the 12 volts is well under the rating of the 120v switch.

How do you dim a 12V DC LED?

Simply connect the two output wires from the power supply to the dimmer unit, and then the two input wires from the LED strip. The dimmer simply acts like a valve, and the power supply unit will automatically provide the rated current and voltage to depending on the dimmer’s knob position.

How do you install a 12V dimmer switch?

Can you use a dimmer on DC?

DC Dimmer Switch 12V or 24V

How does a DC dimmer switch work?

With a dimmer switch, this regular sine wave or curve is chopped up deliberately. When the current changes direction, the light bulb circuit is automatically shut off. The change in direction takes place when there’s zero voltage which happens twice in every cycle (120 times per second).

Can a standard incandescent dimmer be used on a lighting transformer that converts 120 volt circuit voltage to 12 volts for a low voltage lighting system?

MOST cannot. You need to find out what kind of transformers you have and does it require a special lo-vo dimmer.

Can I use a 110v light switch for 12V?

Yes , a standard household light switch will work on 12V if wired correctly,but it sounds like you hooked both wires from the battery to the switch!!

Can you use a 240v dimmer switch for 12V?

Yes you can as long of course within the amp rating of the switch. A standard light switch is rated around 6A which for 230v is about 1.4kw but with 12 volt that is only 72W.

Can you dim a low voltage transformer?

No longer do you have to use a separate low voltage transformer with an inline 120V dimmer to dim your landscape lighting system. The Brilliance LED 12V AC Dimmer can operate inline with any of your low voltage wires.

How do you dim low voltage LED lights?

How to Dim Low Voltage LED Lighting

How does a DC LED dimmer work?

Analog dimming adjusts LED light output by directly modifying the DC current in the LED string, while PWM dimming realizes the same effect by changing the duty cycle of a constant current in the LED string to effectively modify the average current in the LED string.

What is a high side dimmer switch?

Simply put, the “side” is where the dimmer control is. For a high-side dimmer, the dimmer is “higher” or “above” the load (LED) when connected to the 12V power supply. Conversely, a low-side dimmer places the dimmer control “below” or “lower” than the LED, essentially connecting it to Ground.

How do you install a dimmer switch on an RV?

Installing a LED dimmer in my RV

How do you change an RV light switch?

Just kill the power and use some needle nose pliers to pull off the connectors. Squeeze the tabs in on the end of the switch and it will pop right out. Squeeze the new one in and plug the connectors back on the tabs, replace and you are ready to go.

Can I use a dimmer switch to control a motor?

Always buy a switch that is rated to handle an equal amount for the watts or more, not less, in order for the dimmer switch to work well. A dimmer motor AC switch is suitable for a ceiling fan.

Can I use a dimmer switch as a potentiometer?

Rheostats and potentiometers are essentially the same thing. Modern household dimmer switches no longer use variable resistance
typically solid-state modulation is used to dim the light. If your switch is truly a potentiometer, I recommend replacing it with a modern dimmer which is vastly more efficient and safer.

How do you make a dimmer switch a speed controller?

How To Make a Speed Controller from a Dimmer Switch

Can I install a dimmer switch on any light?

A dimmer switch can be installed anywhere that an existing on or off switch is in place. Replacing the current toggle switch with a dimmer switch will allow you to change the lights’ brightness, so long as you are using a light bulb that is compatible with the dimmer you have chosen.

Do dimmer switches work on all lights?

Most light fixtures will work with standard dimmer switches, including those with halogen and incandescent lamps. Determine whether your fixture uses line or low voltage. If you install line-voltage track and rail lights with incandescent bulbs, you can use dimmer switches to control their brightness.

What are the different types of dimmers?

Most dimmers fall into these four bulb type categories:

  • Incandescent and halogen bulbs.
  • Dimmable compact fluorescent light bulbs.
  • Magnetic Low Frequency (MLV)
  • Electronic Low Frequency (ELV)

Do LED lights need special dimmer switch?

A standard dimmer switch cannot be used with an LED light as you will never be able to dim the LED light either completely or not very well. LED lights need their own special electronic dimmer switch to have a fully functioning and dimming light.

Do dimmer switches need special bulbs?

A modern dimmer switch switch functions the same way as if you turn a light ON and OFF really fast. These switches are designed to work with CFLs, Halogens, and Incandescent light bulbs. But the bulbs need to be of the latest technology and must have the feature of dimming to allow it to be used with a dimmer switch.

Why do my LED lights flicker on a dimmer switch?

There are many reasons why an LED lamp can flicker, but the most common cause is a lack of resistance in the lamp to allow the dimmer curve to work correctly. This is not a new issue
it’s been around for a long time, but is becoming more “noticeable” with the major increase in LED usage.

Can I use an AC switch on a DC circuit?

AC is self-extinguishing since the current goes to zero 120 times every second. DC does not so the switch has to survive until the arc dies down on its own. So the DC switch has to be hardier and will therefore work with AC. However, the AC switch is not as hardy and should not be used with DC.

Does a dimmer switch limit voltage?

No. When you dim the lights, you put less current through the bulb by putting a “resistor” in the way. Turning the switch gives a greater resistance, and hence a lower current through the bulb. However, the power that doesn’t come out of the bulb is disappated across this resistor (it will get hot).

Can I use AC light switch for DC?

Yes, an AC switch should be fine to control a few milliamperes of a relay coil. The relay is designed to switch high DC currents.

Can I use 250v switch on 12V?

Yes, there will be no problem. As long as the voltage of 12 Volts is same, it will work perfectly fine on a 12 Volt 1 Amp power supply as it would on a 12 Volt 0.17 Amp power supply.

Will a 12V switch work on 24V?

Non-illuminated switches can be used in a 24V system. You must de-rate a 12V product for a 24V application. Lighted switches cannot be used at different voltages.

What is an architrave switch?

What is a Architrave Switches? Architrave Light Switches are generally used in areas where space is restricted. Often used in between 2 door frames or close to corners or obstructions where a standard switch simply couldn’t fit.
