Abstract: A vehicle power system includes an electrical power source, an electrical bus, and a contactor electrically connected with the electrical power source and electrical bus. The contactor includes first and second poles, dual plungers each operatively associated with one of the first and second poles, and an electromagnetic coil configured to cause at least one of the dual plungers to move if the coil is energized.

Abstract: An apparatus for sensing relative positions of mechanically coupled devices. The apparatus includes a magnetically actuated switch connected to a set of flux conductors to form a switch assembly. A permanent magnet is affixed to a set of flux conductors to form a magnet assembly. The flux conductors are positioned adjacently to conduct flux from the permanent magnet to the magnetically actuated switch. Movement of either assembly results in the reduction of flux conduction between the magnet and the magnetically actuated switch. The apparatus can be integrated into a helmet mount for night vision goggles to sense the relative position of the helmet mount for controlling the operation of the night vision goggle.

Abstract: A gas appliance control assembly includes a gas valve and a reed switch operated simultaneously by rotation of a single shaft. The reed switch opens and closes a circuit including an electronic ignition module and a spark igniter so that spark is provided as the gas valve is adjusted to a burner igniting condition.

Abstract: A switch assembly having an actuator rod for manually actuating the switch, a deactuator rod for manually deactuating the switch and an electromagnet for electrically deactuating the switch.A spring biasing armature is pivotally mounted on a U-frame for movement within the switch housing. A pawl projects from the armature for engagement with a latching shoulder on the actuator rod. When the actuator rod is depressed to an actuated position which closes the switch contacts, the armature pivots to a position in which the pawl latchingly engages the latching shoulder on the rod and retains the rod in the actuated position.The actuator rod is released from its actuated position by movement of the pawl out of latching engagement with the latching shoulder. Release is accomplished manually by depressing the deactuator rod which is mounted in alignment with the free end of the armature.

Abstract: A mode selecting device for a tape recording and/or reproducing apparatus includes a plurality of push-button members which are selectively actuable from rest positions to active positions for selecting corresponding operating modes of the apparatus, an electrically energizable driving means, such as, a solenoid, which is momentarily energized in response to the actuation of a selected one of the push-button members to its active position, an operating member movable by said driving means from an inoperative position to an operative position in response to the momentary energizing of the solenoid and being urged to its inoperative position upon deenergizing of the solenoid, a plurality of transmission members each being coupled with the operating member in response to the actuation of a respective one of the push-button members for establishing the corresponding operating mode of the apparatus by the movement of the operating member to its operative position, a locking assembly for locking the operating membe
