Electromechanical relay with test button

The present invention relates to an electromechanical relay and to a method of testing such an electromechanical relay. An electromechanical relay according to the present invention comprises a contact assembly (106) comprising at least one stationary contact (102) and at least one movable contact (104), an electromagnetic actuator assembly (116) for actuating the at least one movable contact (104), wherein the electromagnetic actuator assembly (116) comprises a coil assembly (116, 120, 122) for generating a magnetic field and a movable actuator arm (110) that engages with the movable contact(104) for actuating the movable contact (104) in response to the magnetic field, wherein the actuator arm (110) is slidable in a direction across to a longitudinal axis of the movable contact (104), and a housing (134) that encases the contact assembly (106) and the electromagnetic actuator assembly (116). The electromechanical relay (100) further comprises a rotatable test button (128) with operating means (130) that can
