ABSTRACT:
The controller comprises a rear sub-assembly to be mounted in a conventional toggle wall switch opening, a conventional toggle switch cover plate with a vertical toggle switch operating arm-receiving slot, the plate to extend over the rear sub-assembly and being of a size to overlap the wall switch opening, and a front sub-assembly to be mounted over the cover plate. An anchoring screw-receiving opening in the rear of sub-assembly is accessible from the front of the front sub-assembly through the cover plate slot. A screw passing through an opening in the front sub-assembly and cover plate slot anchors at least partially the front sub-assembly and the cover plate to the rear sub-assembly. A rotatable and depressible shaft extends from the rear-sub-assembly and passes through the cover plate slot and the front sub-assembly. A timer and on-off switch operating knob removably fits over the shaft to expose the screw when the knob is removed from the shaft.
