LovelyLifeAST LOVELIFEAST Wireless Remote Control Commander Switch Tool For Winch 12V Cordless Car Truck Auto Vehicle

Works and great value for under a tenner. I've used this to add a wireless remote to the Lofrans windlass on my boat. It has four wires (the blue one is actually the antenna) with ring terminals crimped on. Black and red are for the 12V supply. When pushing the in/out buttons on the remote, the black box puts +12V on the yellow or white wire depending on which button is pushed, which is perfect for driving the relays in the windlass control box (or anything else really). Can be hooked up in parallel to existing control buttons or wired remote.The manual was in the usual poorly written English and took some deciphering, making it all sound needlessly complicated. Both remotes worked fine and came with batteries. The remotes are not waterproof, so I put one in one of those phone plastic bags. The remotes have a sliding switch on the side where they must be turned on and off - I don't know how long the batteries last when you forget to turn it off after use, but the manual suggests not that long. Remotes are of cheap but acceptable construction.
