ABSTRACT:
A switch includes three blade contact terminals against which is biased a rotating printed circuit board. The printed circuit board is rotationally moveable with respect to the blade contacts and has conductive elements on a first side of the printed circuit board for selectively contacting the switching contacts in response to the relative rotation between the switching contacts and the printed circuit board. The conductor elements include a tab for extending around the edge of the printed circuit board to a second side of the printed circuit board so as to provide electrically connected regions on both first and second sides of the printed circuit board. An electrically conducting resilient contact abuts the second side of the printed circuit board and biases the printed circuit board against the switching contacts. The tab and resilient contact can be coupled to a ground potential.
