Abstract

The contact breaker for high voltages is provided with automatic spark suppression. The contact breaker has basically two aligned electrodes one of which, automatically, as it moves drives a piston to compress the spark suppressing gas within the electrode breakdown gap. The moving electrode (12) of the circuit breaker penetrates a piston (28) which is moved in the opposite direction to that of the electrode by virtue of two cogged wheels engaging with mating cogs on the electrode shaft (16). Alternately a single lever (32) attached to the rear of the piston is driven by cranked levers (36, 42) fixed at one end to one end cover (18) of the overall switch enclosure (14).
