View Patent ↗A control device having an elongated shaft, a C-shaped magnet, and an anti-rotation pin. The magnet and the anti-rotation pin are encapsulated in a spherical member. The C-shaped magnet has opposing ends defining an open slot along the C-shaped main body. The anti-rotation pin extends through the slot and connects to the shaft.
1. A control device comprising:
an elongated shaft;
a C-shaped magnet having an elongated slot, the magnet formed to receive the shaft in a center opening;
an anti-rotation pin connected to the shaft and extending through the slot of the magnet; and
a spherical member formed to encapsulate the magnet.
2. The control device of claim 1 wherein spherical member is made of zinc.
3. The control device of claim 1 wherein the magnet is made of Neodymium-iron-boron.
4. The control device of claim 1 wherein the shaft, anti-rotation pin, and spherical member are formed of one piece.
5. The control device of claim 4 wherein the one piece is made of zinc.
