Single Channel PWM (pulse wave modulation) dimmers are ideal for operating LED Light Strips and other interior incandescent or LED lighting, such as map lights, convenience, footwell or baggage compartment lighting. Features include reverse-polarity protection and over-voltage protection as well as an integrated on/off switch (in the fully counterclockwise position).
12 Volt DC (14VDC systems) version has 7 Amps of capacity (97W)
24 Volt DC (28VDC systems) version has 4 Amps of capacity (112W)
Just 1.25” x 1.6”. Shaft diameter is 17/64” (6.75mm)
Screw-down terminals for easy connection of input and output wires
Powerful enough to operate a wide range of lighting products
High-quality push-on knob. Shaft length accommodates panel widths to 5mm.
I have had very good luck with this dimmer controlling a vertical compass and a MGL V6 radio and a Garmin GMA240 audio panel. It does what it is suppose to. Installed in a Vans RV7 2 years ago.
Small, easy to instal but seems not as progressive as wanted. But efficient
For instruments and night lights Should work well
I have not had very good luck with these dimmers. Experienced the third failure a few days ago. Application is driving two red LEDs for IP lights. The rotary switch/pot gets draggy and gritty, then soon the unit quits all together. I would rate them inadequate for aircraft service.
Per the supplier: Yes, usually - it depends on the radios and the type of circuit controlling the back lighting.

This unit does not have an OFF detent. When the dimmer is turned off, the power is not cut off completely, a separate switch would be required.
No, these dimmers are not FAA approved. Intended for use in experimental aircraft only.
There is no distinct switch that is separate from the knob, although turning it all the way will go past the "switch" and turn it off. A gently turn past the notch the other way turns it back on.
