Power control apparatus and method

Apparatus for controlling an output power provided to at least one electrical component, comprising:

• at least one module comprising at least one electronic circuit for providing an output power, adjustable via rotation of at least one rotary element, to at least one electrical component when the electronic circuit is electrically connected to an input power supply that supplies power to the electronic circuit;
• at least one first switching element configured to electrically disconnect at least one of said at least one electronic circuit from the input power supply when the at least one first switching element is in a first predefined state;
• and
• at least one actuator element that is rotatable between a first position and a second position and that is configured to switch a respective first switching element to the first predefined state when rotated from the first position to the second position, wherein the at least one actuator element comprises a body portion that comprises a riding surface configured to contact the respective first switching element when the at least one actuator element is in the first position or the second position.
