Hanging pendant light switch with wooden body.
Typically used above a bed to allow the light to be switched without getting up.
Due to age, the wood has dried out, resulting in a long crack on one side.
Some of the original fabric covered twisted flex is still attached.
In one position, a brass block is positioned between the two contacts, connecting them together.
In the other position, an insulating ceramic block breaks the circuit.
The metal rod is insulated from the brass block by a rubber sleeve.
Live parts are exposed inside, even when the switch is in the off position.
As this is a UK item, it would typically be used at voltages up to 250 volts.
The two contacts are spring loaded, with the tapered shape of the sliding part holding the switch in either the open or closed position.
The opposite side has terminals for attaching the wiring.
The central white part is ceramic - an excellent electrical insulator, but also rather fragile. This example is cracked.
Wiring is threaded through the main body, attached to the inner section, and the end cap screwed on.
This video features this wooden switch and several wooden plugs.
