Abstract: A switch has a set of contacts, a rotatable actuator for operating the contacts and a rotatable shaft for positioning the actuator. The shaft extends out of the front of the switch housing and through the actuator to adjacent a rear housing opening. A mounting member is selectively positioned in any one of a number of predetermined positions in the housing and includes a first latch having a different angular position around the shaft for each mounting member position. A second latch on the shaft secures the shaft in a first rotary position until the shaft is moved axially toward the rear of the housing. Removable fasteners secure the mounting member in any of its predetermined positions. With the fasteners removed and the shaft in its rearward position, the mounting member is free to be moved to another of its predetermined positions, which moves the location of the first rotary position of the shaft. An actuator driver carried by the shaft drives the actuator upon rotation of the shaft.
