Zusammenfassung:PURPOSE: An electronic switch and a manufacturing method thereof are provided to prevent a noise of an internal switch in an external case by interposing a filler between the internal switch and the external case. CONSTITUTION: An electronic switch includes an internal switch(100), an external case(200), and a filler(300). The internal switch has a movable part, a gas sealing part, and a magnetic driving part. The movable part has a contact point. The gas sealing part seals an extinguishing gas filling space for extinguishing an arc. The magnetic driving part provides a driving force to the movable part. The external case receives the internal switch. The filler is filled between the internal switch and the external case. The filler is a liquid hardened resin.
