The relay satisfies relatively stringent safety regulations with respect to leakage-current resistance, flashover resistance and mutual influencing between the contact spring sets. Those contact springs (4, 5) which are in each case allocated to one another of the contact spring sets (25, 27) are arranged in chambers (9), which are closed on all sides, in the insulating block (1). One of the walls of the chambers (9) is formed from a wall of a protective cap, the second wall by a separating wall (6) of the insulating block (1), and the third and fourth walls from side walls (7) which are arranged at right angles to the separating wall (6) and are integrally connected to the insulating block (1). At least one restoring element (17) is provided for the entire spring set (2), and the active contact springs (5) are held in the insulating block (1) without being prestressed. <IMAGE> |
