Sierra had switches, pilot lights, and receptacles (ungrounded) that would fit in there and you would get 1,2 or 3 hole coverplates. 126k members in the electricians community. The high-pressure switch is designed to shut down the compressor if the line pressure gets dangerously high. Since 1968, West Marine has grown to over 250 local stores, with knowledgeable Associates happy to assist. I serviced a large estate in the mid seventies that had an extensive low voltage switching system. They went out of business, but were bought by Pass and Seymour who still make the switches and, I believe, the straps needed to install them. Well the switch is a lot cheaper. Touch-Plate systems installed between 1946 and 1985: Previous generation relays had 4 wires, 2 low-voltage wires extruding from the top of the cylinder.
