Abstract

There is described an electromagnetic relay comprising a cover (1) containing a bi-stable test push-button (16), that realizes a temporary and a fixed contact positions; the test push-button (16) is equipped with retainer means (20) to obtain the fixed position by pushing and simultaneously rotating it; and the cover (1) is equipped with means (34) to house the push-button (16) preventing its release in case of fixed closure. Moreover, the cover (39) can be equipped with a slider (40) comprising means (46) to allow temporary pushing and means (42, 44) to allow permanently pushing the push-button (48) into its contact position. <IMAGE>
