ABSTRACT:
A manually actuatable direction controller includes a planar base supporting a number of magnetic reed switches, one of each direction in which control is to be exercised. The reed switches are arrayed about the plane of the base in a symmetrical pattern, with each one positioned in the direction over which it exercises control. A number of permanent magnets are arrayed in one-to-one relationship with the reed switches, with the magnets lying in a plane spaced from and parallel to the switch plane. A sheet of magnetically conductive material is supported for movement in the base between the plane of the switches and the plane of the magnets. An elongated handle has one end connected to the center of the sheet and projects normally from the base. The magnetic field imposed by each permanent magnet on its associated reed switch maintains that switch in a first state. By motion of the handle the magnetically conductive sheet can be moved with respect to any magnet and its associated switch, diverting the magnetic field of the magnet and thereby causing the associated reed switch to change state and effect the control signal provided to an associated direction controller.
