Abstract
An electrical disconnect switch which includes a pair of fixed tubular conductors having tulip connectors mounted on the free ends thereof. The switch includes a pair of movable tubular conductors telescopically engageable with the tulip connectors for completing a circuit through the switch. The movable conductors are spring biased to an opened position and a latch is provided for retaining the movable conductors in a closed position. The switch also includes a solenoid connected across the fixed conductors and designed to operate a lever for blocking movement of the movable conductors to the closed position when a relatively high current is flowing through the solenoid.
