Locking actuators
Open quickly, close easily: With their compact design, HELLA locking actuators are always used when reliable locking and unlocking in confined spaces is required. Examples include fuel filler flaps, glove compartments, or charging plugs on e-vehicles and charging stations.
The actuator is mounted in each case by a simple snap-in assembly. In the electromotive locking and unlocking function, the locking lever uses electrical voltage to move a hinge arm mounted in the locking system. Reversing the polarity results in unlocking. The position of the locking element can be determined by the integrated micro switch. For the electromechanical locking and unlocking function, a return spring and a micro switch are integrated in the locking actuators. The micro switch is actuated by light pressure, e.g. on fuel filler flaps. This resets the actuator locking lever, opens the locking system, and opens the tank or service flap using a spring. After the actuator is switched off, the locking lever returns to the locking position without current. The tank or service flap is then automatically locked after being pressed shut.
