The DS100 is a dual foot switch with one pedal on each side that is attached to a metal base plate with rubber bumper feet. It comes pre-wired with both pedals wired together with a single cable exiting the unit. Each pedal has momentary action and is wired normally open (N.O.), which means that it actuates when your foot is on the pedal, and de-actuates when you release your foot from the pedal. Electrically, the switch on each side is rated 13 amps @ 125/250 VAC. The cable is 8 feet long and is 16 gauge / 4 conductor (16/4) cord, with one wire common to both switches, one wire for the left side, one wire for the right side, and one ground wire (consult an electrician if you are unsure how to connect the wiring). The foot switches are wired so both switches cannot be operated at the same time (neither will work if both are pressed). Also includes a pigtail strain relief to reduce cable fatigue at the entry port, a powder-painted finish, and a low profile to reduce operator fatigue. Ideal for applications involving forward/reverse, up/down, twin pedal, and many more. This model does not have a guard (contact SSC for model DS100-DG if you need the guarded version). Enclosure rating: CSA/NEMA Type 1 and IEC 60529 IP20. For indoor use in dry environments. CSA Certified to US and Canadian standards. Replaces TWIN T-91-SC48 or TWIN 971-SMC48.
