An actuator for a motor vehicle functional unit includes a force transmission unit transmitting an actuating force to an actuating member and being displaced by a measuring travel in a force transmission direction. A force measurement device detects an actual value of the actuating force and includes a spring acting in the force transmission direction, having resilient action counter to which the force transmission unit is displaced and being tensioned by the actuating force over a resilient excursion, a micro switch having smaller switching travel than the measuring travel and being actuated upon displacement of the force transmission unit if the actuating force reaches the actual value, and a stop element for actuating the switch. The switch or element are coupled to or fixed relative to the force transmission unit and the switch and/or element are resiliently supported to compensate for a difference between the switching and measuring travels.
