Review on 🔌 Enhance Lighting Convenience with KITASST 12v DC Touch Dimmer Switch – Remote Controlled for LED RV Lights Interior, Motor, Halogen, Incandescent - Black by Michael Lara

Two problems: 1) On the first day, after 2 hours driving, the front touch glass control panel fell off the plastic rim. The glass is attached with double-sided tape. I filled it with a thin layer of epoxy, I hope it holds up. 2) Mounting: If you cut out the required square piece for the switch, the mounting holes will be in the center of the switch body, which means the screws need to go into the piece you just cut out. When I push the screws through the mounting holes it just goes into dead air. The dimmer works but needs to be connected in a specific way. I need to apply input voltage + and -, I have 12 volt RV, ground minus. In my RV the LED lighting switch was just a battery plus switch, open or closed. Normally you would replace the ON/OFF switch with a dimmer, but this dimmer requires isolation of the positive and negative LEDs, which means you can't just take two (+) wires from your old ON/OFF switch. You also need to find the negative wire of your LED lighting circuit, disconnect it from the rest of your negative RV (ground) and connect it to this dimmer.
