A pin latch includes a housing, a handle attached to the housing, a shear pin attached to the handle, and a finger member attached to the handle and the shear pin. The handle may be set in an intermediate position between open and closed positions. Trigger pins slidably engage slots formed within the finger member until they engage stops to retain the handle in its intermediate position. To further retract the shear pin and move the handle towards the open position, the finger member is lifted and the trigger pins disengage the stops. Alternately, the latch includes a button mechanism having a cross-pin that engages a stop formed by a slot within the shear pin to maintain the handle in its intermediate position. To further retract the shear pin and rotate the handle, the button mechanism is depressed to disengage the cross-pin from the slot of the shear pin. |
