Altech Corp 2ALM3LB-024 Emergency Stop Pushbutton

The Altech Corporation 2ALM3LB-024 is a 22 mm mushroom-shaped illuminated emergency-stop pushbutton with momentary action, featuring a green LED indicator powered from 24 V. The metal operator and mushroom head provide a robust panel-mount solution for control panels and safety circuits, with illumination that serves as a visible status cue when energized. This illuminated pushbutton is designed to be paired with separate switch contacts to create a complete E-stop assembly; up to four switch contacts can be installed with any illuminated operator, with contacts and the operator sold separately. The panel cutout required is approximately 22.5 mm in diameter (round), consistent with other 22 mm Altech pushbuttons in the same family. The 2ALM3LB-024 variant is described as a mushroom illuminated momentary pushbutton, suitable for applications that require a temporary stop or reset action in safety and machine-control circuits, such as machine guarding, conveyors, and panel-mounted control stations where clear, immediate actuator feedback is necessary. This part represents one configuration within Altech’s 22 mm illuminated pushbutton lineup, enabling designers to select the right color, LED voltage, and actuation style for their specific control system.
