Abstract
A latch includes a base, a drive shaft and cam, and a handle attached pivotally to the drive shaft. The handle is moveable between a closed position, a pop-up position, and an open position. A slide plate is attached slidably to the base and engaged with the cam. A swivel arm is attached pivotally to the base and the slide plate. A bolt assembly is attached to the swivel arm, and a plunger is mounted within the base. In its closed position, the handle engages the plunger to engage a switch and the bolt assembly engages a structure. In the handle's pop-up position, the plunger moves to a retracted position and disengages the switch. When the handle is moved to the open position, the drive shaft and cam are rotated so that the slide plate slides and the swivel arm pivots to swing the bolt assembly away from the structure.
