Replace the hinges on access doors or machine guards with these switches to keep your team safe from active machinery. Also known as interlock switches, they automatically shut off power to your machinery when the door or guard opens. They can be mounted on flat frames or aluminum T-slotted framing. These 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. They’re rated IP65 for protection from washdowns.

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.

The convenient, modern alternative to mechanical safety switches. These RFID switches are easier to install, fit a wider range of access points, and can mount horizontally. Since they don't need a traditional key to actuate, they work even if the switch and actuator are slightly misaligned. Also known as interlock switches, they shut off power to equipment as soon as you open the barrier, which disconnects the RFID signal. These switches are often used with small machines. Find them anywhere from a CNC machine’s window to a packaging machine’s service panel. Mount the switch on the frame and the actuator on the barrier. Rated IP67 and IP69K, these switches are protected against temporary submersion and high-pressure, high-temperature washdowns.

The number of safety outputs, also known as output signal switching devices (OSSDs), tells you how many machines you can control. Each output has a pair of signals that shut down a single machine—if one signal fails, the other takes over as a failsafe.

Switches with a magnetic latch help prevent a barrier from opening by accident, such as from light bumps and low vibrations. The magnet keeps the actuator and switch from separating.

Micro M12 cords (sold separately) connect switches to your system’s circuits.

Block access to machinery while it's running. These safety switches cut power when their signal disconnects, shutting off equipment as you open machine guards. They link to a single actuator, so no other RFID tag or card can interfere. The unique RFID code means that once the power is cut, no one can bypass the switch and restart equipment while the guard is open.

These switches are often used with small machines where there’s no risk of the barrier closing on its own. Find them anywhere from a CNC machine’s window to a machine-operated saw’s service panel. Mount the switch on the frame and the actuator on the barrier. They're also known as interlock switches. Rated IP67 and IP69K, these switches are protected against temporary submersion and high-pressure, high-temperature washdowns.
