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 Honeywell 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 the pedal lever and shaft from oil, solvents, and water. 3/4″-14 N.P.T. threaded conduit entry in back. Ideal for factory, shop, metalworking, iron workers, boom lifts, food processing, riveting, bending, and many more applications. Directly replaces Linemaster® Hercules 531-SWH, 531-SWHO, and 531-SWHOX (slight difference in height). UL/CSA/NEMA Enclosure Type 2, 4, & 13. IEC rating IP56. Size: 9.2″ L x 6.2″ W x 5.5″ H. UL Listed and CSA Certified (note: some optional features may be CSA or UL but not both).
