Abstract (en)
[origin: EP0641003A1] An electromagnetic relay includes an electromagnet (14) with a pivoting blade (38), a mechanism (16) with a bell crank (44) intended to drive a bistable rocker contact (20), and an elastic device (56) for returning the blade (38) to a spaced-away position when the coil of the electromagnet (14) is not excited. A link rod (48) is articulated onto the blade (38) and the bell crank (44), and the return device includes a pair of compression springs (58, 60), one of which acts later than the other. A contact position indicator (72) is incorporated within a manual-control test button (70), and comprises an optical prism (78) interacting with a feeler (80) integral with the blade (38). <IMAGE>
