The GX500-MO is a heavy-duty foot switch that has the same construction as the G-Series, but without the guard. Features all-aluminum construction, precise switching action, 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). 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. UL/CSA/NEMA Enclosure Type 2, 4, & 13. IEC rating IP56. Size: 8.4" L x 4.2" W x 2.5" H. UL Listed and CSA Certified. One year warranty on parts and labor. Made in the USA by SSC Controls Company.
