This is a resin cast replica of a vintage ceramic style light switch. It is a solid resin casting of the real thing. It is NOT made of ceramic nor is it a functional switch. The top has a "bakelite Brown" colored top. It also includes 4 resin cast faux insulators. These are for theater and display use only. They are not intended to be used with "live" wires. Great for your vintage theater set or haunted house display. The base of the switch measures approximately 2" diameter. DO NOT USE AS AN ACTUAL INSULATOR FOR HIGH VOLTAGE LINES!
