Abstract

The replacement unit includes a magnet circuit support magnetic barrier member which includes the magnet unit of a Hall generator and is adapted to be fastened to the contact interrupter plate. The unit also includes a distributor rotor adapted for mounting on the contact interrupter cam of the distributor shaft. A plastic reinforcing member of higher mechanical strength is anchored in the distributor rotor. It has a keying projection and extends over the region surrounding said projection, thereby reinforcing the critical section of the distributor rotor. Preferably it is cap-shaped and has an opening for accommodating a retaining member which retains the distributor rotor in the desired position.
