Abstract
A selector switch assembly includes modular switch units that are serially-arranged in a housing and are operated by a single rotatable control member that is biased to a first position by a biasing unit. A modular switch unit includes a housing that has an end wall and two opposite sidewalls that each have two recesses at opposite ends which receive planar blade portions of switches to define an enclosure. The control member includes a hollow tube that has a friction member which has cams on the periphery to actuate the switches and also has an opening for frictionally engaging a rotatable adjusting screw on the next modular switch unit. The modular units are sealed into a support and the hollow tube provides access to the adjusting screw outside the support.
