MECHANICALLY OPERATING ELECTRICAL PULSE GENERATOR

摘要

A mechanically operating pulse for generating electrical pulses dependent upon the rotation of direction of rotary shaft. The pulse generator includes a gear rim having internal toothing driven by the rotary shaft, a radially and generally deflectable switching sleeve which has a cam which engages in a tooth space of the gear rim. A spring member supports the switching sleeve on its side opposite the cam. Metal contacts are disposed adjacent to end areas of the spring member in such a way that said end areas are movable into contact with the metal contacts. A contact stud is disposed centrally of the spring member such that it mechanically retentions it in such a way that each end area is pressed against its adjacent metal contact and the cam is pressed into a tooth space of the gear rim. When the rotary shaft is rotated by one tooth, an end area of the spring member is moved into or out of contact with its adjacent member.
