Abstract
In a relay according to this invention the terminal elements (17) are injection-molded into wall members (2,3) which are so designed that they during assembly, and if so required, together with parts of the flange (35) of the coil (16) of the electromagnetic driving system, form a cup-shaped member having a bottom part (4). The rim portion (9) of the cover member (1) which is capable of being placed thereon, projects over the bottom part (4). The thus resulting space may be filled with a sealing compound (casting resin) (13). From this there results a tight relay consisting of a few individual parts only, which is easy to manufacture and which, moreover, is solder- and wash-tight.
