ABSTRACT:
In a pulse generator with a rotor (7) provided with a conductive pattern and fixed contact springs wiping over the pattern, the latter is formed by a central continuous slip ring (15) which is concentric with the drive shaft (3) of the rotor (7) and has inwardly and outwardly projecting teeth (16; 17), the number of internal teeth (16) being equal to the number of external teeth (17), and the internal and external teeth having the same angular spacing (.alpha.). A fixed contact (32) slides on the slip ring, and two fixed impulse contacts (33, 31) slide on circular paths (K1, K2) formed by the internal teeth (16) and the external teeth (17), respectively, and the internal teeth (16) are staggered with respect to the external teeth (17) and/or the two fixed impulse contacts (31, 33) are displaced in relation to one another such that at least in one direction of rotation of the rotor (7), the fixed impulse contacts (31, 33) cannot simultaneously make contact with a tooth (16, 17) of their circular paths (K1, K2) or with the flank of such a tooth.
