A motor timer comprising a casing, an electromagnet disposed within the casing, an instantaneous switch and a timing switch disposed on opposite sides of the electromagnet within the casing, an actuating member extending laterally above the electromagnet and operatively connected to a movable core associated with the electromagnet, spring means normally urging the actuating member away from the electromagnet, a timing gear operatively connected to a motor through a reduction gearing and a clutch unit, and a locking lever extending vertically above the timing switch for normally maintaining the timing switch in the locked position. The instantaneous switch can be immediately actuated in response to the energization of the electromagnet, while the timing gear acts to trip the locking lever with predetermined timing while rotation for unlocking the timing switch from its locked position so that the timing switch can be actuated for timing operation.
