ABSTRACT:
A guidance system for an interrupter switcher comprising a first guide positioned in between the contact support and the movable contact system of the interrupter, and a second guide inserted into the stationary contact system of the interrupter. According to the invention the second guide is capable of receiving the nozzle of the movable contact system. An interrupter with the guidance system is assembled by positioning the first guide between the contact support and the movable contact system, positioning the second guide within the stationary contact system, inserting the nozzle of the movable contact system into the second guide, and mounting the stationary contact system in the interrupter housing. The assembly of an interrupter with a guidance system results in a self-adjusting switcher interrupter capable of maintaining a stable alignment between the interrupter's movable and stationary contacts while opening and closing the interrupter.
