PROBLEM TO BE SOLVED: To make a control device more stronger in structure than a conventional joy stick and higher in reliability even in a sevior environment without deteriorating performance. SOLUTION: The method of forming the control device includes the steps of positioning a magnet and a shaft in a die and die-casting zinc around the magnet and the shaft. The magnet is a sintered C-shaped magnet having opposing ends defining an open slot along the C-shaped main body. An anti-rotate pin is positioned in the die and is located at least partially within the open slot. Zinc is die-cast around the magnet, the shaft and the anti-rotate pin. COPYRIGHT: (C)2007,JPO&INPIT
