Latest Patents

Strand's latest patents include innovative designs for electrical switches. One of his patents describes an electrical switch that features a frame, an operating shaft, and a bridge member that moves in a depth direction relative to the frame. This movement is achieved through the rotation of the operating shaft, which exerts a first opening force on the bridge member during an opening event. Additionally, the switch incorporates an anti-tilting member that moves laterally, providing a second opening force to the bridge member. This design enhances the switch's reliability and performance. Another patent outlines a neutral contact adjustment system that allows for precise positioning of the neutral contact opening surface relative to phase contact opening surfaces. This system can operate in two states: a simultaneous break operation and a late-break operation, improving the safety and efficiency of electrical disconnections.
