Abstract: A rotary circuit selection device (400) having a driving cam (430) and an operating cam (440), each having a series of alternating peaks (442) and valleys (455). A biasing mechanism (420) biases the driving cam toward the stationary cam such that the peaks of one cam are received by the valleys of the other cam and vice versa. Selection of an alternative circuit includes rotating and translating the driving cam in relation to stationary cam.

Abstract: A panel mounted low profile rotary switch (100) contains a detent mechanism (120) mounted in a bushing (110). In a preferred class of embodiments, the detent sub-assembly comprises a single spring (220) positioned in parallel within the vertical extending shaft (130). The force exerted by the spring is manually adjusted by a set screw (210) to provide the desired downward applied vertical force on a plunger (230). The plunger, preferably a pointed cylinder, applies pressure to detent balls (240) causing the detent balls to move radially outward and engage rotor cams located on the inner surface of the detent mechanism.
