The Piranha™ Micro Switch 0531616 is a replacement limit switch located in the front control box assembly of most Piranha™ ironworkers. This switch helps control the upstroke and downstroke travel limits of the ironworker to ensure safe and consistent operation.
This micro switch functions as an ironworker limit switch, activated by adjustable limit switch arms that operators set manually to control the desired stroke position during punching, shearing, and notching.
Most Piranha™ ironworkers require two micro switches per machine.
