Replace access door hinges with these switches; they actuate when the door opens at least 4°. Also known as interlock switches, they ensure the safety of personnel by automatically shutting off power to machinery when an access door opens. All have positive-force, normally-closed contacts that will open a circuit when the switch is actuated even if a spring fails or the contacts stick. In addition to access doors, these switches can also be used on machine guards constructed from aluminum T-slotted framing. They’re rated IP65 for protection from washdowns.
