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.
