An electromagnetic relay has a coil body (1) which supports a, magnet system, and a base. The coil connection elements (3 4), which connect the coil body to the base are fastened to the coil flange (11, 12) by horizontal fastening branches (33 34, 35, 43, 44), in matching insert channels (13 14, 15, 16, 17) in the coil, flange (11 12). Wind-on pieces (36, 46) which carry the ends of the coil winding directly are formed on the coil connection elements (3, 4). The relay can therefore be manufactured simply and automatically from a small number of components.

Why it's free to use
- Filed December 3, 1990. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended December 3, 2010.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by December 3, 2012.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
