Choosing an Electrical Switch

Snap-Acting Switches

Open and close circuits quickly to minimize arcing and prevent contacts from sticking. These switches are often used as door-open indicators on appliances and enclosures.

Harsh Environment Snap-Acting Switches

With a rubber-encased housing and stainless steel bracket, these switches resist vibration and corrosion. They're rated IP68 for protection from dust and temporary submersion.

Enclosed Washdown Snap-Acting Switches

Rated NEMA 4 , these enclosed switches have a sealed actuator for protection from washdowns.

Enclosed Snap-Acting Switches

Enclosures protect these snap-acting switches from the environment.

Mil. Spec. Washdown Snap-Acting Switches

Keep out dirt and moisture—the sealed housing on these switches is watertight and meets MIL-PRF-8805.

Enclosed Wet-Location Snap-Acting Switches

Rated IP67, these switches have an enclosure that shields their interior during temporary submersion. They open and close circuits quickly to prevent arcing and keep contacts from sticking.

Miniature Snap-Acting Switches

Smaller than standard size snap-acting switches, these fit in tight spaces.

Subminiature Wet-Location Snap-Acting Switches

Built for tight spaces exposed to water, these switches have a housing that's less than 1" long and IP67 rated for protection from temporary submersion.

Subminiature Snap-Acting Switches

At least 25% smaller than our Miniature Snap-Acting Switches, these switches are often used to trigger actions from inside a vehicle’s door or an engine compartment.

Light-Touch Subminiature Snap-Acting Switches

Actuate these switches with a fraction of the force of other subminiature switches for increased responsiveness. Among the smallest snap-acting switches we offer, they fit into the tiniest of spaces.

Ultra-Miniature Snap-Acting Switches

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.

Circuit Board Magnetically Actuated Switches

Mounted to your circuit board, these switches trigger when magnetic components get near, and reset as they move away.
