Abstract
An interlock assembly is provided for a fusible switch which has a fuse in series with a switch and an operating mechanism for controlling the operation of the switch. The interlock assembly is mechanically coupled to the operating mechanism and includes an indicator member disposed adjacent to the fuse for indicating the status of the fuse and an actuator member mechanically coupled to the operating mechanism for actuating the operating mechanism to open the switch when the fuse is BLOWN. A toggle member is coupled to the indicator member and to the actuator member for mechanically communicating the status of the fuse to the actuator member from the indicator member wherein the toggle member is in one position when the fuse is CONDUCTIVE and the toggle member is in another position when the fuse is BLOWN.
