Choosing an Electrical Switch

Key Shown Actuating from the Side

Also known as interlock switches, these ensure the safety of personnel by automatically shutting off power to machinery when an access door opens. Mount the switch to the door frame and mount a key to the door so that the key is inserted into the switch when the door is closed. When the door opens, the key is removed from the switch and the machine shuts down. They’re often used with machine guards.

Style A-G switches 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.

NEMA 6 rated switches protect against temporary submersion and washdowns.

NEMA 4 rated switches protect against washdowns.

IP67 rated switches protect against temporary submersion.

Flexible keys (sold separately) pivot 15° to make it easier to align with the switch during installation.

Access-Delay Frame-Mounted Safety Switches

Key Shown Actuating from the Side

Delay access to hazardous areas until conditions are safe; use these switches with machines that take time to stop after they are turned off. Mount the switch to the door frame and mount the key to the door so that the key is inserted into the switch when the door is closed. When the door is pulled, the key is held in place with 225 lbs. of force until the switch receives a signal from a time-delay relay, motion sensor, or position sensor (not included) that the machine’s motion has stopped. After the motion has stopped, the key can be removed from the switch, releasing the access door. They’re often used with machine guards. 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. They’re rated for protection from washdowns and temporary submersion.

Style A and B have a key entry on the top and side of the switch.

Style C has a key entry on two opposite sides of the switch.

Emergency override keys (sold separately) bypass the access delay feature.

Hinge-Actuated Safety Switches

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.
