FIELD: electrical engineering.
SUBSTANCE: invention relates to device for switching off electric current, such as switches or disconnectors-load switches. Electrical switch contains module of mechanism and module of contacts. Contact module contains base element, lid element, fixed contacts and pivot roller for receiving moving contacts. Mechanism module comprises base member, lid member, front tubular shaft for controlling switch from front side, inner tubular shaft for controlling side switch from the side. Tubular shafts are coupled to each other by teeth to form drive to transfer torque from the front tubular shaft to inner tubular shaft. Switch also includes lever for transferring moment to roller. Lever is configured to receive inner tubular shaft. Inner tubular shaft and lever are rotatably engaged with each other, and main springs, designed to communicate torque to lever, are connected by first ends to base element, and to lever with their second ends.
EFFECT: increase in efficiency of circuit breaker.
