Abstract

1. A switching mechanism for an electrical installation switch, in particular for an earth-leakage circuit breaker, having a release-gear position, at which a contact area on a release lever (18) is pressed resiliently against a contact area on a ratchet lever (12), characterized in that the contact area on the ratchet lever (12) and/or on the release lever (18) is convex towards the other.
