1. A solenoid system for moving a filter in a camera, comprising:

  • a solenoid;

    an armature in moving communication with the solenoid, the armature having first and second operative positions;

    a first contact segment engaging the solenoid when the armature is in the first operative position;

    a second contact segment engaging the solenoid when the armature is in the second operative position; and

    a filter mounted to and moving in unison with the armature,wherein energizing the solenoid moves the armature between the first and second operative positions, the solenoid being de-energized when the armature is in each of the first and second operative positions and wherein the armature is self-stable in each of the first and second operative positions such that one of the first and second contact segments of the armature biases toward and abuts the solenoid while the solenoid is de-energized.
