1 All SPST switches are set to normally-open operation in their "dry", "no level"
condition unless specified otherwise. "White-Red" and "White-Yellow" denote single
white wire with red or yellow stripes.
2 Each switching point requires one float. For special applications, a single float can
be used to activate two switch points, though these points must have a minimum
separation of 1/8" (3 mm). The maximum number of actuation levels depends on the
wiring type selected.
3 Standard Lead Wires are 24" long, 18 or 22 AWG, UL-approved Teflon
