Patent ID: 8179215

Claim:
A lid assembly for a micro-switch having a lid assembly and a base assembly, the lid assembly comprising: a substrate; a first insulating layer formed on the substrate; a first conductive layer formed on the first insulating layer; a signal path formed in the conductive layer and having a gap for preventing signals from propagating on the signal path; an actuator formed in the first conductive layer for providing a force on a movable structure in the base assembly when the actuator is activated; a second insulating layer formed on the first conductive layer; an insulating ring formed in the second insulating layer; a second conductive layer formed on the second insulating layer; and a conductive ring formed in the second conductive layer, the conductive ring substantially aligned with and overlying the insulating ring, the conductive ring forming a seal around the movable structure when the lid assembly is bonded to the base assembly.
