H operators are attached to the door jackshaft to indirectly drive the door.

The hinge linkage is arranged that minimum pressure is required to activate the electrical control switch causing door to reverse direction of travel to the fully open position.
Reverse switch is enclosed in a galvanized housing with a sliding plunger to assure positive actuation every time.
