ABSTRACT:
An electromechanical actuator system for use in an aircraft in high frequency electromagnetic environments is disclosed. The system includes an electromechanical switch which responds to a control signal to actuate a device on the airplane. A pair of capacitors is installed in the control signal circuit and the indicator light circuit of the switch within a switch housing. These capacitors cooperate to suppress electromagnetic radiation and voltage transients emitted by the switch. A low pass filter line cable is attached at one end to the switch and at its other end to the source of the control signal and other devices on the aircraft. The individual conductors of this cable are electrically insulated, and these insulated conductors are encased in an electrical shield which is also electrically insulated. To protect the system from high frequency electromagnetic interference, this cable is over 12 inches long, and substantially the entire periphery of the shield is grounded at both ends of the cable.
