ABSTRACT:
The present invention relates to a fusible switch for use in a multiphase circuit. The switch includes an operating mechanism which is secured to the enclosure of the switch and provides for a handle to operate the opening and closing of switch contacts. Movement of the handle stores energy in the operating mechanism which is subsequently released in a quick motion just as the switch contact is to be opened or closed. The switch also provides for heat sinks and means for venting the enclosure to dissipate the heat created from the higher voltage and greater current density carried by this improved switch.
