A single-piece construction prevents the contact block from separating from the actuator in high-vibration applications.

Sized for 4 mm or 6 mm panel cutouts, these switches are often used with circuit boards to control electronics.

Operate low-voltage devices that require less than 48 volts, such as doorbells and buzzers.

A protective plastic enclosure resists dents, chips, and cracks, so you can install these switches outside of panels.

These familiar push-button switches mount to flat surfaces.

With a slim shape, these switches fit comfortably in your hand.

Use this switch for intermittent, light-duty applications.

Reset fire panels, or open electromagnetic locks, electric strikes, and automatic door openers. These switches require a key to turn circuits on or off, limiting access and preventing accidental activation.

Tug the hanging rope to actuate these switches.

Pull the chain to send a switch signal. These switches are commonly used as replacements in lights and fans.

Trigger actions in devices as small as phones and drones. The smallest snap-acting switches we offer, these switches fit into the tiniest of spaces and help keep weight to a minimum.

Combine an actuator and a switch to assemble the exact limit switch you need.

A sealed actuator prevents these switches from jamming, even when exposed to sand, mud, or dirt. With a slim design, you can stack them together or fit them in tight spaces.

Protect machinery and ensure the safety of personnel—these switches will open the circuit when actuated even if a spring fails or the contacts stick.

Delay access to hazardous areas until conditions are safe; use these switches with machines that take time to stop after they are turned off. They mount to a door frame.

Set these switches to delay activation by up to five seconds after detecting an object.

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.

Sealed for safety, these relays are a good choice for hazardous locations where combustible or corrosive gases may be present.

Reduce connection errors on circuit boards that control machine guards and other safety devices. These relays take up less space on a board than those with electrical wiring because their solder pin terminals mount directly through circuit board holes.

These relays pair the transmission reliability of an interface relay with the fail-safe operation of a safety relay. They have interlocking contacts—also known as force-guided or mechanically linked contacts—so opposing contacts won't close at the same time.

Monitor phase, voltage, and frequency at the same time to protect motors, generators, and other three-phase circuits from burning out or overheating.

Detect and mitigate ground faults to prevent harm to equipment, circuits, and people.
