ABSTRACT:
An electric switch for use in a five-pole isolating switch used as a phase inverter has a fixed contact and a mobile contact cooperating with the fixed contact to open or close an electrical line. The mobile contact is moved in a longitudinal direction by an articulated pair of levers. An isolating switch used as a phase inverter having five switches comprises a single three-position actuator for maneuvering the mobile contacts through a linkage.
