Description

Micro-switches are often found in arcade buttons and joysticks but they're also really handy in any kind of mechatronics project or when you need a basic sensor. They are always 'tactile' (clicky feeling), and 'momentary' (the switch closes when pressed, then snaps open once released). They come in a few different varieties (mostly having to do with the contacts and how big the actuator is).

This microswitch has a flat metal lever actuator and a roller at the end. The roller makes it a little better for angled actuation. This switch comes with three terminals (common/normally-open/normally-closed). Adafruit also have kinds with a bump actuator, flat lever and long wire. This is a basic micro switch for arcade and mini robots, and they don't have any detailed specifications for it so this switch is recommended for use with 30VDC and 250mA max.
