This is a replacement base for large porcelain knife switches used in high school basic electricity units (physics or science classes). The original porcelain base (Leviton 125V, 25A) is very fragile and many have been accidently broken over the years. This PLA base works perfectly (and is a cheap replacement). Since PLA canot withstand high heat, this base should not be used with high voltage or current. It is however perfectly safe (and durable) for 1,5V - 6V used in class.
