Abstract
A high current fusible disconnect switch device includes a switch housing configured to receive a pluggable touch-safe fuse module, and a dual slide bar actuator assembly for opening and closing switch contacts. The dual slide bar elements are each coupled to bias elements that store and release energy to affect switch opening and closing operations. The switch opening and closing operation is multi-staged wherein the only the first slider element is movable in the first stage, and both the first and second slider elements are movable in the second stage.

1-36. (canceled)
A fusible disconnect switch device comprising:
- a switch housing configured to accept a removable fuse;
- a line side terminal and a load side terminal in the switch housing;
- a switch actuator selectively positionable between an opened position and a closed position;
- and
- a slider assembly linked to the switch actuator and responsive to the position of the switch actuator to effect a switch closing operation or a switch opening operation via selective positioning of at least one switch contact to make or break an electrical connection to one of the line and load side terminals;
- and
- a first pair of bias elements acting upon opposing sides of the slider assembly to store and release energy to affect at least one of a switch closing operation or a switch opening operation.
