Abstract

The panel mounted low profile rotary switch includes a knob, a detent sub-assembly, a shaft, a bushing, and a panel. The knob is held to the shaft by one or more locking screws and the operation of the detent sub-assembly is enclosed and is not altered by removal of the knob. The entire detent sub-assembly is located on the knob side or user's side of the panel. Only the bushing and the shaft extend through the panel. The shaft is connected to a rotary component such as a rotary switch contact which engages circuitry on a printed circuit board. The switch or electrical connection is located on the undersurface of the panel.
