The CT41/42 Electronic Wiper Switches control one or two wipers and fit into standard dashboard switching systems (like Carlingswitch). Turn wipers on and off, control speeds (low, high, plus 3 levels of intermittent) and trigger wipe/wash capabiliities all in a tiny package. The CT41 and CT42 compact, stand-alone switches work with Exalto, Coastal Series, W38 and most other popular brands of wiper motors.
