A lamp socket and cable bracket assembly includes a lamp socket holding a lamp bulb, electrical wires extended from the lamp socket for connection to power source, and a flat cable bracket configured to hold the electrical wires in a smoothly curved manner against stretching and to dissipate heat radiated by the lamp bulb, avoiding electrical wire damage. The motor is mounted in the housing. A hardmask with a top layer and sidewall layer is formed over the organic mask. In addition, the actuator is operably connected to the control valve by at least a hydraulic linkage, where the hydraulic linkage compensates for changes in the actuator and the injector body due to changes in temperature. In this way effective fastening of insulation packages to objects in an aircraft cabin may be ensured without all the insulation packages having to comprise openings for accommodating fastening pins.
