This switch box can be used for anything that uses a standard C13 / C14 power entry. I'm using it to switch the power brick for my Prusa i3. The holes near the bottom can be used to zip tie the enclosure to another object. The components need to be wired together before inserting into the box as there is no lid or other openings. I only switched the live wire, neutral and ground are wired directly to the output socket.

I used the following components:

Quantity 1 each
Q226-ND
Q209-ND
Q947-ND
EG1509-ND
Any of these switches will also work

I soldered all the connections but crimped quick connect terminals can be used as well. See A27817-ND for 18-22AWG or A27824-ND for 14-16AWG.
