The L-2-S is Lektro-Lok foot operated switch operates on the teeter-totter principal. Mechanical interlock-prevents both circuits from being operated at the time. Pressure on one side opens or closes line, release of pressure returns switch to normal off position, pressure on other side open or closes circuit, independent of first. Both switches can be wired normally open or normally closed. All wiring connections are made internally with only a single cord being brought out. This eliminates costly harness assemblies which combined with the attractive switch price offer real economy.
