Miniature Snap-Acting Switches
Smaller than standard size snap-acting switches, these fit in tight spaces. They open and close circuits quickly to minimize arcing and prevent contacts from sticking. They’re often used as door-open indicators on appliances and enclosures or as an internal component in limit, pressure, and temperature switches.

Light-Touch Subminiature Snap-Acting Switches
Actuate these switches with a fraction of the force of other subminiature switches for increased responsiveness. They’re a good choice if you need reliable actuation even from a light touch. Among the smallest snap-acting switches we offer, they fit into the tiniest of spaces. To minimize arcing and prevent contacts from sticking, they open and close circuits quickly. They’re often used as door-open indicators on enclosures or as internal components in limit, pressure, and temperature switches.
Switches with a plunger actuator require a push to actuate.
Switches with a roller lever actuator allow parts to glide across the actuation surface with less friction than standard levers. This prevents wear and tear over time.

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. They open and close circuits quickly to minimize arcing and prevent contacts from sticking. They’re often used as door-open indicators on appliances and enclosures or as internal components in limit, pressure, and temperature switches.
Switches with a plunger actuator require a push to actuate.
Switches with a lever actuator have an arm that increases the size of the actuation surface.
Switches with a roller lever actuator allow parts to glide across the actuation surface with less friction than standard levers. This prevents wear and tear over time.

Snap-Acting Switches
Open and close circuits in a snap. These switches actuate quickly to minimize arcing and prevent contacts from sticking. They’re often used to indicate that an appliance or enclosure door is open. You can also use them inside limit, pressure, and temperature switches.
Switches with a plunger actuator require a push to actuate, similar to a button.
Switches with a roller lever actuator combine the larger actuation area of a standard lever with a smooth gliding roller actuator. They minimize friction to limit wear and tear on your switch.
