Abstract
Systems, devices, and methods disclosed herein can generally include electrical contacts for high voltage, high current, and/or fast acting electromechanical switches and methods for manufacturing the same. The electrical contacts can be optimized for high voltage blocking capabilities with minimal gap spacing in the open state and low electrical resistance when in contact in the closed state. Electrical contacts can have a geometry to produce a low peak electric field between the contacts when in the open state, have a high contact surface area when in the closed state, and a low mass. The geometry of the contacts can be based on geometries traditionally utilized for uniform field electrodes.
