Abstract

Reed switches 10 are mounted in parallel-spaced fashion on printed circuit board 11. Rotatable, magnetic cylindrical shield 12 extends along board 11 close to switches 10. Permanent magnet 13 is disposed within shield 12 and is movable along the interior. Shield 12 contains window 14 that extends along switches 10. Shield 12 is effective when rotated to a position between magnet 13 and switches 10 to allow magnetic flux from magnet 13 to actuate any adjacent switch 10.

Selector Switch

Reed switches 10 are mounted in parallel-spaced fashion on printed circuit board 11. Rotatable, magnetic cylindrical shield 12 extends along board 11 close to switches 10. Permanent magnet 13 is disposed within shield 12 and is movable along the interior. Shield 12 contains window 14 that extends along switches 10. Shield 12 is effective when rotated to a position between magnet 13 and switches 10 to allow magnetic flux from magnet 13 to actuate any adjacent switch 10.

The selector switch is actuated by two actuators 15 and 16. Actuator 15 controls rotation of the shield and is thus operative to control the on-off operation of the selector switch. Actuator 16 controls the position of magnet 13 and is thus effective to select which switch 10 is to be actuated.

The selector switch can be operated in many different modes. For example, with the shield in the off position, magnet 13 can be positioned adjacent the desired switch 10 so that when shield 12 is subsequently turned on, such switch 10 is closed. Another mode is to initially rotate shield 12 to the on position and to then move magnet 13 so as to actuate all or some of switches 10 in series dependent upon the length of the path of movement.
