Abstract

An interrupter for activation of an electrical signal hooter has group of platelets joined at one end with isolating layer and connectors. Contacts are carried on plates of which one is static and the other movable and carrying a contact and an isolator. The group of plates is mounted in a carrier head and electrical inputs are connected by cable grip connectors and controls the action of electromagnets which vibrate the carrier shaft of the hooter. The stipulated loading can be reached to avoid too much wear and unstable working caused by the spark generation. The loading adjustment and the mechanical construction can be achieved in a single working process which is easily made automatic.
