ABSTRACT:
A cam follower is pivotally mounted on an electrical contact blade. The cam follower provides a ramp surface when engaging a step of the cam and a sharp drop off when dropping from a step. The ramp surface provides a smooth transition from a lower surface while the sharp drop off provides for a quick make and break of electrical contacts.
