Triple Axis Magnetic Actuator Through Non-Metallic Substrate

摘要

A magnetic actuator can be slid in the X and Y direction along a housing or other substrate, and depressed in the Z direction, where desired, activating a button. This is accomplished by way of magnetically engaging one, two, or more ring magnets on either side of the substrate, defining a plane. Central magnets are placed within these ring magnets and can be held in place further by a circumferential sleeve between the central magnet and the ring magnet, as well as between a ring magnet and the substrate. By arranging the polarities of the magnets, the central magnet on one side of the substrate is held away from the substrate, while, on the other side, the central magnet is held against the substrate.

1. A three-axes magnetic actuator comprising:
a first ring magnet with portal and a first central magnet at least partially within said portal of said first ring magnet; a second ring magnet with portal, and a second central magnet at least partially within said portal of said second ring magnet; said first ring magnet and said second ring magnet arranged with opposite magnetic polarities pointing towards each other on either side of a non-magnetic substrate; wherein in a resting state, said first central magnet is spaced apart from said non-magnetic substrate. and said second central magnet is closer to said substrate than said first central magnet.
