Actuator system comprising at least one actuator, a control unit, a power supply and an operations panel, where the actuator in a transmission between an activation element () and a reversible electric motor is inserted a quick release unit () for release of the activation element () from the electric motor and the part of the transmission between the motor and the quick release. The actuator comprises at least one electrical switch (), activated with the quick release. The signal from the electrical switch(es) () may be used for various purposes, such as triggering a power supply from sleep mode, activating one or more actuators, or activating an external function such as an alarm etc.

Actuator assembly and bed

Actuator comprising of a quick release unit and a means for determining the position of an activation element. With the quick release unit it is possible to release the activation element from the actuator's electric motor and the transmission or, at least part of it, to make a rapid adjustment to the activation element without the motor and transmission. The means typically used for determining the position of the activation element comprises of a potentiometer, an optical or magnetic encoder indirectly driven by the motor. By connecting the instrument for position determination () to the spindle () or the part of the transmission between the quick release and the spindle (), the position of the activation element remains known regardless of whether it is released or connected, or has been released.
