The G500-MO is a heavy-duty foot switch that makes it easy to turn electrical equipment on and off with the foot, freeing the hands to perform other operations or providing ergonomic improvement to a workstation. 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). This is a momentary foot switch, which means that it actuates when your foot is on the pedal, and de-actuates when you release your foot from the pedal. Includes a single 20-amp 125/250VAC-rated switch with one common, one normally open, and one normally closed contact (SPDT, Form C). Side cover flaps help protect pedal lever and shaft from oil, solvents, and water. 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 don't already have a strain relief. Ideal for factory, shop, metalworking, iron workers, boom lifts, food processing, riveting, bending, and many more applications. UL/CSA/NEMA Enclosure Type 2, 4, & 13. IEC rating IP56.
