Abstract

A pulse generator having a gear and an actuating member. The actuating member is made from insulating material. It is movable sideways and is forced against the gear by a compression spring, which also serves as a detent spring. This forces a projection into engagement with a tooth space in the rest position. The pulse generator is especially suited for producing current and voltage pulses for digital tuners.
