売れのこったブラウン管のおはなし。(1624) 水銀スイッチ

$A diagram of a mercury switch with two green and orange tubes connected to a white cylindrical device with metal contacts. Text in Japanese reads "水銀スイッチ" (Mercury Switch) and includes additional labels and descriptions about the switch\'s function and structure. A cartoon character with a red bow and white hat appears twice, with a curious expression and text bubbles in Japanese.$
