Old porcelain and wood switch

Charming and old thick white porcelain switch with a wooden lever. It probably dates from the beginning of the 20th century, maybe earlier. The mechanism seems to work, it stays well in both positions, one making the connection, the other not. I cleaned the visible side but not the mechanism inside. It has two holes to attach it to the wall. On the side, two small holes allow access to two small screws to connect the electrical wires inside. At these holes, the porcelain is a little rough with a little coloring, original or not, I don't know). And in the same place but on the rear edge a location (originally it was perhaps two holes but it seems to be missing a piece of porcelain, the two holes therefore become one, larger) allows to pull out the electrical cable. The wooden lever could be refinished. It measures 5.5 cm in diameter, 3.5 cm in height.
