Choose an actuator and contact block to make your own switch. All switches are rated for protection from washdowns and oil/coolant spraying. NEMA 4X rated switches are also protected from corrosion. Use legend plates (not included) to label switches.

Key actuators are keyed alike, so they will all open with the same key.

Switch guards protect flush and projecting switches from accidental activation.

Choose an actuator and contact block to make your own switch. All switches are IP and NEMA rated for protection from dust, washdown, and chemicals. For an easy way to tell switches apart without labels, choose them based on their actuator color.

Push-button actuators are best for applications where you need quick starts and stops. Those that are illuminated make switches easier to see in low light. They require a contact block with a bulb holder. For yellow actuators, use a white bulb. If wiring the switch and the bulb to the same circuit, the circuit voltage must not exceed bulb voltage.

Lever actuators must be gripped and twisted to activate. This means they’re a good choice in areas where you don’t want switches to activate if someone accidentally bumps into them.

Key actuators prevent accidental activation because they require a key to turn on and off. They are keyed alike, so they will all open with the same key.

Contact blocks with mounting latch accept additional contact blocks to control more circuits.

Choose an actuator and contact block to make your own switch. All switches are rated NEMA 4, 13, and IP65 for protection from washdowns and oil/coolant spraying.

Actuators spring back (momentary), but can be wired to stay switched (maintained).

Add a bulb to illuminate actuators. If wiring the switch and the bulb to the same circuit, the circuit voltage must not exceed bulb voltage.

Use removal tools to replace bulbs, lenses, and contact blocks.

Mounting wrenches make it easier to install switches in crowded panels.

Our most sensitive limit switches, these switches actuate with the slightest push for a high degree of accuracy. They’re often used for determining manufacturing tolerances and detecting minute expansions and contractions. When an object pushes into the plunger actuator, it sends a signal to open or close a circuit. Install them in a standard panel cutout.

IP67 rated switches are protected from temporary submersion. They’re ideal for wet locations.

Sealed actuators prevent these switches from jamming, even when exposed to oil, sand, mud, or ice. They send a signal to your circuit when an object hits the actuator—for instance, a box on a conveyor runs into the switch, stopping the conveyor. They open and close circuits as fast as snap-acting switches, but they have a bigger actuator for large objects. To actuate, they require a push, similar to a button. Rated IP68, they’re protected against dust and temporary submersion.

Switches with a stainless steel housing stand up better to wear and tear and corrosion better than switches with a zinc-plated steel housing.

Combine an actuator and a switch to assemble the exact limit switch you need. These switches have the rapid-closing action of a snap-acting switch, but have a larger actuator for large objects. When an object in motion comes into contact with the actuator, it sends a signal to open or close a circuit. They’re often used for conveyor systems and elevators. Each actuator style is compatible with all housing styles and vice versa.

Roller-plunger actuators open or close circuits when an object pushes against the roller, which moves the plunger. The roller helps push the plunger even if the force isn’t straight on. The roller also reduces friction during actuation which prevents wear and tear over time.
