Slap a power switch on any cord with this easy to print 2 part housing. A small ziptie holds the assembly together and acts as strain relief. The clamshell design means you have easy access without having to cut or re-solder the wires. Three sizes included for the following switches. These are fairly ubiquitous and will work at pretty much any voltage. They should be easy to find on Ebay or in electronics you may already have laying around. These are what I ordered from Amazon, though some seem to be unavailable at this time: Small https://www.amazon.com/dp/B01EWGMTME?psc=1 Medium https://www.amazon.com/gp/product/B00VG9GYZ4/ref=oh_aui_detailpage_o03_s01?ie=UTF8&psc=1 Large https://www.amazon.com/gp/product/B008X10YRC/ref=oh_aui_detailpage_o03_s00?ie=UTF8&psc=1
