If it requires power, you need to know how much, what all the pins do, and how to hook it up. You may need to reference datasheets, schematics, and know the ins and outs of electronics.
Skill Level: Competent - You will be required to reference a datasheet or schematic to know how to use a component. Your knowledge of a datasheet will only require basic features like power requirements, pinouts, or communications type. Also, you may need a power supply that?s greater than 12V or more than 1A worth of current.

This is a pretty solid switch all around. It stays in place really well, and the bevel around the front hides a bit of error on the filing I did to make a rectangular hole.
The only problem is that it has to be wired backwards from what you'd assume. The center post is tied to one side or the other depending on the position of the switch, yes, but the post beneath the on symbol is actually open when the switch is "On". So to make a complete circuit when the switch is on, you have to solder to the center post, and the one beneath the off side.
To put it simply, check it with an ohm meter before you solder!
