Review on Compressor Pressure Unloader LF10 4H 1 NPT1 4 95 125 by Tarus Clinton

Lefoo LF10-4H has a four port distributor. 4H designates four openings in the manifold. I bought the LF10-4H to replace the LF10-4H on my Craftsman air compressor. I wanted the connectors to match exactly so I didn't have to modify any of the connectors, air or electrical. When I received the LF10 from Revain, I noticed two differences from my OEM switch. First, the alignment of the collector was shifted by 90 degrees. Second, the air charge valve was straight, not the 90 degree angle of my OEM switch. I moved the bootloader from the OEM switch to the new one and the problem was fixed, but the switch still wasn't properly aligned. There isn't much discussion on the internet about rotating the collector, so I gave it a try. I have found this to be possible but very difficult as the switch is spring loaded and it is very difficult to squeeze the spring loaded switch while it is still placed in the bracket with the bootloader. Finally, I modified the derailleur body and used some fishing line to compress the spring while I inserted the derailleur into its mount. After the modifications I managed to align all the connections. The switch worked perfectly and there were no more problems with the compressor cycle.
