Abstract

Three-pole positionable compact isolator switch for medium and high voltage, set in a rack structure (11) at a crossbar element (13) which acts as a guide element for a case (14) of a circuit breaker group (15), the case being rotatable with respect to the rack structure (11) and translatable, once rotated, with respect to and within the crossbar element (13) between an operative position contained within such crossbar element and a non-operative position extracted from such element (13), the circuit breaker group (15) being arranged between upper connectors and lower connectors (16, 17) integral with the crossbar element (13), inside the case (14) an operating stem (18) being translatable for the engagement and disengagement of a movable contact (26) and a fixed contact (29) for each pole, wherein each movable contact (26) is maintained in the engagement and disengagement positions by the collaboration of return springs (24, 45), identifying the various positions by means of a respective forked square lever (10) connected by means of pivoting (19) to the operating stem (18).
