A motor-driven time limit relay including electromagnetically controlled relay contacts, in which motor driving and contact control sections are separated by a base plate. The electromagnet of the contact control section is secured laterally to one side of said base plate. The yoke extends from an end secured to the electromagnet core to the other end, along upper face of the magnet and, at the extended end of the yoke, an armature is pivoted. A plate actuator likewise extends above the magnet and is coupled at one end to the armature for integral movement with the latter. The other free end of the actuator is normally biased to its lower position of the armature's de-attracted state. A sliding member for controlling the relay contacts positioned above the actuator is slidably mounted to a guide means secured to the other opposite end of the magnet to the armature, and is coupled to the free end of the actuator. Upward movement of the actuator free end at the time of armature attraction allows the sliding member to slide upward for relaying operation, but the sliding is normally locked by a locking lever secured to the guide means until a preset limited time reaches.
