    Plastic Enclosed Lever Switches

    Image of Product. Front orientation. Lever Switches. Plastic Enclosed Lever Switches.
    The enclosure not only protects these switches, but also adds options for how you install them. Secure them to a wall or use the knockout to attach a cord grip and cord, so you can move them around your workstation. Made of polycarbonate plastic, the enclosure resists denting, chipping, and cracking. It’s also NEMA rated to withstand corrosion, washdowns, and spraying oil or coolant. Since you have to twist the lever to actuate these switches, they won’t accidentally flip if someone bumps into them. Choose switches based on their actuator color for an easy way to tell them apart.

    Plastic Enclosed Push-Button Switches

    A protective plastic enclosure resists dents, chips, and cracks, so you can install these switches outside of panels. Mount them on a wall, for example, or tether them to a cord at your workstation. They actuate with a push for quick stops and starts. All are NEMA and IP rated to protect against corrosion, washdowns, and oil/coolant spraying. All have knockouts or integrated conduit connections to make it easy to attach conduit or add cord grips.

    Flush Push Button—Flush buttons are easy to clean and difficult to damage because they mount flat.
    Mushroom Push Button—Mushroom buttons stick out and are often used to stop equipment because they are easy to push.
    NEMA 3S Enclosure Rating—Switches rated NEMA 3S will also work in cold temperatures and when covered in ice.

    Joystick Switches

    Intuitively steer and position cranes, robot arms, and other machinery that moves in multiple directions—your equipment will follow the movements you make with these joysticks. They control multiple circuits as you move them in different directions and patterns. Assemble a complete switch with an actuator and at least one contact block (sold separately).
    Actuators
    Image of Product. Front orientation. Joystick Switches.
    Image of Product. Front orientation. Joystick Switches. Lockable.

    Lockable

    All actuators include a mounting clip that can fit up to two contact blocks. They’re NEMA and IP rated for protection from dust, washdowns, and oil/coolant spraying.
    2 Positions—Two-position actuators require one to four contact blocks.
    4 Positions—Four-position actuators require two to four contact blocks. They are off in the center position.
    Lockable—Lockable actuators have a head that secures in place, so they won’t start if you bump them on accident.
    Momentary Switch—Momentary actuators can only be locked in the off position.
    Maintained Switch—Maintained actuators can be locked in any position.

    Made of yellow polycarbonate plastic, these enclosed switches are easy to see and resist dents, chips, and cracks. They are more corrosion resistant than aluminum enclosed switches and withstand washdowns and oil/coolant spraying. Mount them to a wall or attach a cord grip to position them at your workstation. They have positive force contacts that will open a circuit when actuated, even if a spring fails or the contacts stick. A single push will immediately cut power.
    The switches can be reset by manually pulling, turning or unlocking them by key.
    Key Reset—Key reset switches are keyed alike, so if you buy multiple switches they will all reset with the same key.
    With Guard—Switches with a guard prevent accidental actuation. To stop the switches from being reset or turned on during machine repairs, lock the guard with a padlock.
    Power Indicator—Switches with a power indicator alert you from the front and sides when the switch has been actuated.

    Immediately cut power with a single push. The large palm-sized buttons on these switches provide an easy target, so they're easy to use even while wearing gloves. When the button is depressed, the switch latches and can be locked in that position using a lockout or padlock with a 9/32” shackle diameter (not included). All have positive force contacts that will open the circuit when actuated even if a spring fails or the contacts stick. They're rated NEMA 13 and IP65 for protection from oil/coolant spraying and washdowns.

    Halt machinery in an instant with these tablet holders. They equip your tablet with safety switches that meet IEC and EN standards, so you can safely move around your equipment while teaching robots or monitoring production lines and conveyor systems.
    The emergency stop switch on the front of the holder illuminates when the switch is enabled. There is also a deadman switch on the back of the holder that controls machinery when you lightly press and hold it in the middle position. If the switch is released or pressed down all the way, it stops the machine.
    Pivot the handle to hold a tablet vertically or horizontally, while keeping the switches in a comfortable position for either hand. The adjustable mounting bracket secures a variety of tablet sizes. Connect your tablet to the USB port to charge during use.
