The 532-SWHO is a Hercules series heavy-duty foot switch that provides momentary, single-stage DPDT circuit operation. Constructed with a cast iron treadle and housing and protected by a strong cast aluminum 'O' shield, it is built for strength and durability in harsh environments. This switch is rated for 20A at 125-250 VAC and 1 H.P. at 125-250 VAC, and features an IP56 degree of protection, making it drip-tight, dust-tight, watertight, and oil-tight. The rugged enclosure, which includes a standard 3/4"-14 N.P.T. conduit entry and mounting holes, is ideal for industrial applications where reliable foot control and operator safety are paramount.
