    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 for large robots.
    Style B—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.
    IP67 Enclosure Rating—IP67 rated switches protect against temporary submersion.
    NEMA 6 Enclosure Rating—NEMA 6 rated switches protect against both temporary submersion and washdowns.
    Key Included—All switches require an actuator key, but not all include one—check whether you need to pick out a separate actuator key. For some switch styles, you can also select the mounting orientation of the key.

    Install these limit switches where changing a battery or routing wires might be difficult—they power themselves when a moving object contacts the actuator. Place them up to 330 ft. away from the receiver (sold separately). These switches have the rapid-closing action of a snap-acting switch, but with a larger actuator.
    Plunger Actuator—Plunger actuators open or close circuits when objects push against them.
    Roller Plunger Actuator—Roller plunger actuators open or close circuits when an object pushes against the roller, which moves the plunger. The roller moves parallel to the mounting direction, so it helps push the plunger even if the force isn’t straight on. The roller also reduces friction during actuation which prevents wear and tear over time.
    Roller Lever Actuator—Roller lever actuators open or close circuits when material moves across the switch. The roller reduces friction during actuation which prevents wear and tear over time.
    Rod Actuator—Rod actuators open or close circuits when material pushes against the rod. The rod extends from the body of the actuator, so these switches are ideal when objects actuating the switch are further away.
