High-Visibility Plastic Emergency Stop Enclosed Push-Button Switches
A red light flashes when the actuator is pushed, making it easy to see from a distance. These switches immediately cut power with a single push. They're housed in a protective yellow enclosure for quick identification. All have positive force contacts that will open a circuit when actuated even if a spring fails or the contacts stick. They're rated IP65 for protection from water projected by a nozzle.
Note: If wiring the switch and the bulb to the same circuit, the circuit voltage must not exceed bulb voltage.
Auxiliary contacts allow you to add a signaling device or control another switch.

Corrosion-Resistant Washdown Pendant Switches
Control cranes and other mobile machinery in dirty, outdoor, and wet environments without damaging your switch. The plastic housing is rated NEMA 4X to protect the switch interior from dust, sprayed water, and ice. They are also rated NEMA 12 for keeping out oil and other liquid drips. All of these switches can be wired to prevent two buttons from operating at the same time.
Two-speed switches have staged contacts. For slow speed, press the button halfway down to close the first contact. For high speed, push it all the way to close the second contact.
Use labels to replace worn stickers or change the function of a button. Packs include 28 commonly used functions, such as up, down, start, and stop.

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.

Frame-Mounted Safety Switches
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-F 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.

Access-Delay Frame-Mounted Safety Switches
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.
Emergency override keys (sold separately) bypass the access delay feature.

Magnetically Actuated Switches
These switches actuate when a magnet comes within sensing distance, and reset when the magnet moves away. They’re often used to detect when a door or window opens. Mount the switch in a stationary position, such as a door frame, and mount the magnet to a movable object, such as the door. They do not include a safety relay and cannot be used with safety-guard doors found on machinery.

Tilt Switches
Often used as position indicators, pump level controls, and machine limit switches, these switches actuate when tilted to a certain angle. They mount horizontally and activate when tilted downward, and deactivate when tilted up. Differential angle is the total angle from the point of activation to the point of deactivation. All combine electromechanical and solid state technologies for reliability and long life.

Solid State Screw Terminal Relays
With no moving parts, these solid-state relays are fast switching and require less maintenance, last longer, and are quieter than mechanical switches.
Heat sinks disperse heat to increase the relay’s current rating. Mount them to 35 mm DIN rail (also known as DIN 3 rail) for fast installation. They also mount to flat surfaces. Before mounting one-circuit relays, silicone compound should be applied between the heat sink and relay. Silicone is sold separately for 75A and 90A one-circuit relays. Two-circuit relays don’t require silicone for mounting.

PCB-Mount Relays
Solder these relays directly to printed circuit boards using their solder pin terminals. They're smaller than relays with electrical wiring, so they'll fit in compact devices. They allow low-power circuits to control high-power components, such as heaters and fans.
Solid state relays have no moving parts, so they require less maintenance and last longer, switch faster, and are quieter than mechanical relays.

DIN-Rail Mount Solid State Interface Relays
With no moving parts, these solid state relays last longer, switch faster, and are quieter than mechanical relays. They interface between your controller and components to isolate input and output circuits, which protects components from voltage spikes, amplifies the relay’s signal, and reduces interference for reliable transmission. The included relay socket mounts on 35 mm DIN rail (also known as DIN 3 rail) for fast installation. Relays disconnect from the socket for easy replacement. Rated IP20, they prevent fingers and other objects from touching live circuits.

Solid State Spade-Terminal Relays
Often used for high-speed switching at low-current levels, these solid state relays have no moving parts, so they switch faster, last longer, and are quieter than mechanical switches.
Relay sockets mount directly on 35 mm DIN rail (also known as DIN 3 rail) for fast installation. Relay sockets with screw terminals can also mount to a flat surface. Relay sockets with spring-clamp terminals connect and disconnect to wires without needing to turn screws. Insert a slotted screwdriver into the wire-release slot to free the spring clamp holding the wire in place.

Safety Relays with Diagnostic Capabilities
Control and diagnose issues with safety-critical circuits. These relays have a microprocessor that monitors safety components, such as emergency stops and light curtains, and sends a signal to stop the operation if a failure is detected and restart when the issue is resolved. They also help with diagnostic tasks because of their feedback circuit, which allows basic relays to communicate their status back to the safety relay. These relays have a duplicate set of input and output signals, so they’ll still stop the controlled device if one of the inputs fails.
IP20 rated, they have recessed terminals which prevent fingers and other objects from touching live circuits. These relays have been tested to multiple safety standards and can help achieve PL, SIL, or CAT system ratings. They also meet ISO and IEC standards for machine safety.
Mount them to 35 mm DIN rail (also known as DIN 3 Rail) for fast installation.
Auxiliary contact blocks (sold separately) allow you to control more components, such as signaling devices or basic relays.
