MEMS dual substrate switch with magnetic actuation

Systems and methods for forming a magnetostatic MEMS switch include forming a movable beam on a first substrate, forming the electrical contacts on a second substrate, and coupling the two substrates using a hermetic seal. A shunt bar on the movable plate may close the switch when lowered onto the contacts. The switch may generally be closed, with the shunt bar resting on the contacts. However, a magnetically permeable material may also be inlaid into the movable plate. The switch may then be opened by placing either a permanent magnet or an electromagnet in proximity to the switch.

Systems and methods for utilizing pow switching to synchronize with a rotating load

A control system may include a processor that may receive a first dataset associated with power properties of a rotating load device coupled to a relay device. The processor may also determine frequency properties based on the power properties and determine a switching profile to control moving a first armature of three armatures in the relay device based on the frequency properties. The switching profile is configured to control movement of the first armature between a first position and a second position, and wherein the switching profile comprises a firing angle for moving the first armature with respect to an electrical waveform, a second armature, and a third armature. The processor may then control a current provided to a relay coil of the relay device based on the switching profile, such that the relay coil causes the first armature to move.
