Abstract

A circuit breaker and/or earthing switch are disclosed wherein a rotatable spindle nut, which is mounted in a spindle housing, displaces a spindle in a translatory manner, thus displacing contact elements of the switching device. The spindle actuates a contact pin that is configured in a contact carrier by a connection yoke that is common to all phases or poles and an isolating bar for each phase or pole.
