McGill 1503-0300 Roller Lever Limit Switch is a roller-actuated limit switch used for end-of-travel sensing in industrial machinery. It supports a 20 Amp, 1 HP electrical load rating and carries the E54 designation. It is intended for detecting the position of moving parts on conveyors, presses, and other automated equipment, where the roller lever engagement signals the control circuit to stop or reverse motion. The 1503-0300 provides mechanical actuation through a roller lever, facilitating integration into control circuits that rely on end-of-travel signaling.
