Abstract
A mechanical coupling mechanism links an access door, a push-to-start button, and a switch controlling power to machinery behind the access door. The coupling mechanism permits the door to be open and the switch to be open, the door to be closed and the switch to be open, and the door to be closed and the switch to be closed, while forbidding the door to be open and the switch to be closed. The coupling precludes an operator shifting from a condition with the door open and the switch open to that in which the door is closed and the switch is closed with a single action.
