ABSTRACT:
A first aspect of the invention includes a power relay assembly having a motor assembly and actuator assembly disposed in a housing. The actuator assembly includes at least one bridge assembly having one or more contacts arranged to provide selective electrical connections. The actuator assembly is attached to an armature of the motor assembly. The armature is arranged and disposed to drive the actuator assembly. The motor assembly includes an electromagnetic coil assembly disposed around at least a portion of the armature. A magnetic pole piece is configured adjacent to an end of the coil assembly. The pole piece includes an armature seat configured to attract and receive the armature when the coil assembly is magnetized. The armature seat has a taper configured to provide a substantially constant attractive force along the stroke length.
