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.
Claims19
A rotary circuit selection device, comprising:
- a driving cam and an opposing stationary cam each having a series of alternating peaks and valleys and further wherein the driving cam and the opposing stationary cam have peaks wherein the peaks and valleys have angles formed by converging sides having angles that are substantially equal;
- a biasing mechanism configured to bias the driving cam toward the stationary cam such that the peaks of each cam are received by the valleys of the opposing cam;
- the peaks and valleys of the cams extending towards each other along a translational direction of motion of the driving cam;
- and
- a shaft that rotates and translates the driving cam in relation to the stationary cam in order to select the circuit.

A method of changing a circuit, the method comprising the steps of:
- providing a driving cam and an opposing stationary cam, the driving cam rotating about an axis, and each of the cams having a body and a plurality of alternating peaks and valleys that extend outward from the respective bodies parallel to the axis and further wherein the peaks and valleys are radially spaced along the entire circumference of the driving cam and the opposing stationary cam;
- selecting a first circuit by aligning particular peaks with particular valleys;
- and subsequently
- selecting a second circuit by torquing the driving cam relative to the stationary cam in order to align other peaks with other valleys.
