Circuit Board Push-Button Switches
 |  |  |
Ungrounded, Flush Push Button | Ungrounded, Projecting Push Button | Grounded, Flush Push Button |
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.

Miniature Snap-Acting Switches
 |
Push-Button Actuator Style |
Smaller than standard snap-acting switches, these switches trigger actions in tight spaces. They’re used in components as small as computer mice and engine restart switches. They open and close circuits faster than other switches, preventing contacts from sticking by reducing the time that they're near one another. These switches also minimize the chance of arcing, so electricity won’t jump across contacts.
Push Button Actuator—Switches with a push-button actuator stick out more than switches with a plunger actuator, so they’re easier to activate.
