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 two terminals. Normally they are not connected, when actuated they short together. We also have kinds with a bump actuator, roller lever and long wire. 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.

Technical details

Terminals are 0.187″ wide
