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...

Add a bunch of high-power outputs to a microcontroller system with chainable shift registers. These chips take a serial input (SPI) of 1 byte (8 bits) and then output those digital bits onto 8 pins. You can chain them together so putting three in a row with the serial output of one plugged into the serial input of another to make 3 x 8 = 24 digital outputs. You can chain pretty much as many as you want. This makes it easy to control a lot of...

Keep it cool with a Peltier module. These unique electronic components can generate a temperature differential when powered. That is to say, apply 12V to the red (positive) and black (negative) wires and one side will get cold while the other side gets hot. For best results, you'll need to wick away that heat (otherwise the cold side will slowly get warmer). A fan and/or heatsink is ideal. This module is a 12V module, and is rated for ~72W...
