1. A fusible disconnect switch device comprising:
a switch housing configured to accept a pluggable fuse module;
a line side terminal and a load side terminal in the switch housing;
a switch actuator selectively positioned between an opened position and a closed position;
an actuator bias element comprising a first end and a second end opposite the first end, the first end acting on the switch actuator and the second end coupled to the switch housing; and
a slider assembly linked to the switch actuator,
wherein the slider assembly comprises a first slider and a second slider each slidably movable with respect to the switch housing along a linear axis, the first slider is independently movable relative to the second slider, the second slider carries at least one switch contact to make or break an electrical connection to one of the line and load side terminals, a first bias element acting on the first slider and a second bias element acting on the second slider, and the second bias element is mechanically isolated from the switch actuator in a first stage of a switch opening operation,
wherein the actuator bias element and the slider assembly are responsive to position of the switch actuator to effect a switch closing operation and the switch opening operation,
wherein the actuator bias element moves independently from the slider assembly.
