ABSTRACT:
Rotary switches, and in particular riser-style commutators, are detailed together with featured strips from which they are made. Segments formed from the strips may include anchor notches and slots for receiving reinforcing rings. The structure of the strip additionally permits electrical isolation of adjacent riser segments to occur through its coining rather than through slotting.
