A non-common-ground bandpass filter circuit with electrostatic discharge (ESD) protection is disclosed. The non-common-ground bandpass filter circuit with ESD protection includes a non-common-ground plane, a dielectric substrate and a conductor. The conductor is disposed above the non-common-ground plane. The dielectric substrate is disposed between the conductor and the non-common-ground plane. The non-common-ground plane at least has a first ground region and a second ground region separated and insulated from each other. The first ground region corresponds to a first terminal of the conductor and the second ground region corresponds to a second terminal of the conductor. When an ESD event occurs on one of the first ground region and the second ground region, the other of the first ground region and the second ground region will not be damaged by the ESD event. The non-common-ground bandpass filter circuit also provides surge protection.

A system may comprise a printed circuit board (PCB) including a top surface, and a bracket including a top surface configured to receive and couple to a key switch and a bottom surface including at least two protrusions that extend normal to the bottom surface of the bracket. The bracket can be configured to mount to the PCB such that the bottom surface of the bracket is coupled to the top surface of the PCB, and the at least two protrusions may each include conductive leads that couple to the top surface of the PCB. The bracket is configured to only cover a portion of a bottom surface of the key switch when coupled to the key switch. An LED can be mounted to the top surface of the PCB, laterally adjacent to the bracket, and under the key switch at a location not covered by the bracket.

A lightning grounding apparatus that includes a pivot arm and an electrical grounding element at the distal end of the pivot arm. An actuator is mechanically coupled to the pivot arm and configured to rotate the pivot arm about an axis so as to swing the distal end of the pivot arm between a retracted position and an extended position that is configured to make physical contact between the electrical grounding element and a surface of a structure to be grounded. A limit switch is provided that is mounted on the pivot arm, and is responsive to a position of a limit switch operating arm. The limit switch operating arm is configured to trip the limit switch in response to a predetermined amount of force against the distal end of the pivot arm resulting from physical contact being made between the electrical grounding element and the surface of the structure.
