Heavy-duty foot switch for industrial, factory, and shop applications. Includes oversized guard, rugged housing, and precision switches. The G502-AT includes an Anti-Trip safety latch inside the pedal cover – simply push the latch forward with your toe before pressing down on the foot pedal. The pedal then has a momentary action, which means you have to keep your foot on the pedal to keep it activated, and when you remove your foot it will return upright to the original position. Features all aluminum construction, an oversized guard (5.5” high, 6.2" wide) with enough room to fit large boots, and an oil/water/splash/dust-resistant enclosure (when used with the proper cable clamp). Includes a two 20-amp 125/250VAC-rated switches with one common, one normally open, and one normally closed contact on each switch (together they are DPDT). Each switch can be adjusted to go off at the same time, or at different times as you press down on the pedal (it comes with both set to go off at the same time). 3/4"-14 N.P.T. threaded conduit entry in back. Also see the SSC Controls C1 Cable Clamp or C2 Cable Clamp if you need a strain relief. Cross Reference: Hercules 511-B2, 511-B2O, 511-B2OX. UL/CSA/NEMA Enclosure Type 2, 4,
