Abstract
In a contactless switch, a magnet is mounted on a rod for movement against the action of a spring to actuate a Hall effect switch. A contactless joy stick switch comprises a rod (20) supported and normally maintained in alignment with an axis (22) by an elastomeric spring (28). A plurality of Hall effect switches (42) are mounted in a circular array around the axis for actuation by a magnet (26) mounted on the rod upon displacement of the rod out of alignment with the axis. A contactless push button switch comprises a magnet (86) supported on a rod (74) which is supported for sliding movement along an axis (78) against the action of a spring (82). Displacement of the magnet (86) actuates a Hall effect switch (94). Another contactless push button switch (100) includes magnets (106, 108) positioned to actuate a Hall effect switch (110) upon sliding movement of a rod (74') against the action of a spring (82').
