Abstract
A circuit interrupter characterized by a pair of separable contacts with operating means for opening and closing the contacts and comprising a cylinder and piston mechanism which cylinder has opening means at each end of the cylinder chamber. Rotatable means are provided at each end of the cylinder and have a plurality of spaced chambers which are sequentially alignable with the opening means. Means are also provided in each chamber for generating a sudden expulsion of gas against the piston and the rotatable means at each end of the cylinder being simultaneously rotatable. The circuit interrupter is also characterized by an adapter means for converting the gas from a high to low pressure status to operate the piston.
