Adafruit Micro Switch - Premium Zippy 3-Terminal
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 small bump actuator, but we also have kinds with a lever, roller lever and long wire. Compared to the other 'generic' micro-switches we carry, this one is higher quality and has better specifications. This is a basic micro switch for arcade and mini robots, and we don't have any detailed specifications for it so this switch is recommended for use with 30VDC and 250mA max. A great replacement for arcade controls.
