Abstract of the Disclosure 1. ISOLATING SWITCH FOR METAL-CLAD, COMPRESSED-GAS INSULATED HIGH-VOLTAGE SWITCHGEAR 21. Due to the relatively slow actuation of the main contact pin (3) of an isolating switch (1), it is customary to provide a spring loaded auxiliary contact pin (7) situated inside the main contact pin (3). In the same way as the main contact pin (3), this auxiliary contact pin (7) comes to abut against amating contact (28) and remains there at the beginning of the opening movement until it is returned to the neutral position with a velocity that is greater than the movement of the main contact pin (3) by the spring (8) after being released by a mechanical control unit (14). 22. The mechanical control unit (14) contains a rotatably supported lever arrangement (15), which locks automatically in the neutral position and retains the auxiliary contact pin (7) until it is released by a guide surface (21) connected to the main contact pin. The mating contact (28) of the auxiliary contact pin (7) is also spring-loaded and follows this auxiliary contact pin (7) somewhat after being released, initially while maintaining the equipotential bonding. 23. The isolating switch is advantageous for metal-clad, compressed-gas insulated high-voltage switchgear, whose function is to switch the magnetizing currents in transformers. DC1-32719
