As on some models automatic switches turn on back after switching off, in case of an overload in a chain, the switched-off switch for a moment will disconnect a chain, and then, will return it to the working condition. If the switch back does not turn on, immediately check an electric chain. Do not forget , however, that some automatic switches after operation need to be returned in an initial state manually.

After elimination of a source of malfunction in a chain, the automatic switch will normally work.
