Abstract
A relay with a safety spring set such that the spring contact sets are arranged in chambers, which are freely accessible from the outside via openings when the cover is removed so that the spring contact sets can be manipulated. To prevent broken pieces from ending up in the other regions of the relay in the event of breakage of the contact springs of the spring contact sets, the cover has inwardly directed projections which seal the openings of the chambers when the cover is in place.
