ABSTRACT:
A digital pulse generator including a circular housing having a cover and a base. The base including at least one contact terminal secured therein. The digital pulse generator further including an encoder disc secured within the cover and rotatable relative to the base. The encoder including a plurality of projections formed on a first side of the encoder disc such that each of the plurality of projections defining a ridge and a valley. A ball positioned adjacent to the first side of the encoder and adapted to roll between the ridge and the valley. The ball coupled to a flexible contact and adapted to alternately engage the at least one terminal contact when the ball is adjacent to the ridge.
