    Choose a switch with the right trigger type, number of inputs, and control functions to power your equipment.

    Aluminum Enclosed Push-Button-Actuator Emergency Stop Switches

    These aluminum switches are rated NEMA 4, NEMA 13, and IP66 for protection from washdowns and oil/coolant spraying. Housed in a yellow enclosure for quick identification, they immediately cut power with a single push. They meet EN 60947-5-1 for compliance with European machine directives for emergency stop applications. All have positive force contacts that will open a circuit when actuated even if a spring fails or the contacts stick. UL listed and CSA certified, they also meet American and Canadian safety standards. The front of these switches is UL recognized.
    Key Reset (2 Keys Included)

    Key reset switches stop you from accidentally resetting the switch before you’ve dealt with the emergency. They’re keyed alike, meaning they all open with the same key.

    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.

    Additional contact blocks can be added to control more circuits, or replace the included contact block.
    Make or break an electrical circuit. These contact blocks mount to manual switches and transmit an electrical signal when the switch actuator is engaged. You can stack multiple blocks, so a single switch can control several circuits. This is helpful in setups that require multiple systems to turn on or off at the same time. For example, the switch on a conveyor line could turn off the conveyor and turn on a diverter and alarm.

    Bracket Kits

    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.
    Tablet Holder Bracket Kits—Tablet holder bracket kits enlarge the bracket to hold tablets with thick covers and protectors.
