Easy-to-Assemble Thumbwheel Switch
■Dustproof construction ensures highly reliable performance at low voltage and very small current even under adverse environmental conditions
■Switch units can be assembled simply by fitting the integral hook coupler of each unit into the mating unit, thus eliminating the need of bolts and nuts for assembly
