Choosing an Electrical Switch

Circuit Board Push-Button Switches
Send a signal from your circuit board with the push of a button. These switches are small and have pins for through-hole soldering, helping you eliminate wiring and save space on your circuit board. Also known as tactile switches, they’re the same ones you press when typing on a keyboard. You’ll also find them in control panels and interfaces.
Covers fit over projecting button switches.

Limit Switches







When a moving object contacts the actuator on these switches, they open or close a circuit. They have the rapid-closing action of a snap-acting switch, but with a larger actuator. This makes them a good choice for use with large objects—for instance, a box on a conveyor runs into the switch, stopping the conveyor.
Switches with a plunger actuator require a push to actuate, similar to a button.
Switches with a roller plunger or cross roller plunger actuator have a roller that moves when an object pushes the actuator. This reduces friction during actuation to limit wear and tear on your switch. On cross roller plungers, the roller moves perpendicular to the mounting direction.
Switches with a roller lever actuator use a lever with a roller at the end to activate. This allows parts to glide across the actuation surface with minimal friction, limiting wear and tear on your switch.
Switches with a rod actuator use a rod extending out of the body to actuate, so they’ll activate even if an object is far away.
Switches with a wobble stick actuator have an arm that rotates 360°, so you don’t need to align it in a specific direction. Since the actuator is flexible, it won’t snap if pushed backward. That makes these switches a great choice for systems that get jammed often.
Styles E and F let you adjust the actuator’s height to align it with your target.
Switches rated NEMA 13 are protected against dirt and oil/coolant spraying. Switches rated IP67 are protected against dust and temporary submersion.

Panel-Mount Light-Touch Limit Switches

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.
