<p>A surface-mount pointing device (10) controls the movement of an object on a display screen. The device has a base (50) and a shaft (12). The shaft is mounted to the base. Several sensors (R1-R4) are mounted on the base and around the shaft for sensing the amount of strain in the base that is created in response to a force applied on the shaft by a user. Conductors (56) are mounted on the base and electrically connected to the sensors. Electrical leads (60) are electrically and mechanically connected to the conductors. The electrical leads are shaped for mounting on the surface of a circuit board. The electrical leads each have a bifurcated inner terminal (61) end that is electrically connected to the conductors. The bifurcated inner terminal end fits over and grips an edge of the base. An outer terminal end extends outwardly of the base and is shaped for mounting on the surface of a circuit board (21).</p> |
