Abstract
A power relay having an actuator with a microelectromechanical systems stator assembly and plunger assembly that moves along the central longitudinal axis between a first position and a second position, the plunger assembly including a plunger that includes a pair of ferromagnetic plates with a magnet situated therebetween, and a first ferromagnetic plate of the pair of ferromagnetic plates is situated between first and second ferromagnetic layers in the stator assembly and a second ferromagnetic plate of the pair of ferromagnetic plates is situated between the second and third ferromagnetic layers in the stator assembly. Contacts formed by the ferromagnetic plates and ferromagnetic layers may include an array of micromachined flexures or a stabilized liquid-solid electrical contact.
