What the sign says

The general motorway limit. The green motorway sign alone triggers it; the disc only serves as a reminder.

The exam trap

On an expressway the general limit is 100 km/h, not 120: the blue sign without the bridge symbol is the only clue.

The signs are the official depictions by the Federal Roads Office, from the annexes of the Signalling Ordinance (SR 741.21): official works, unprotected under Art. 5 of the Copyright Act. The explanations, by contrast, are written from federal law — never taken from a third-party catalogue.
