Abstract
A switch mechanism includes a support; a plurality of switches connected to the support. An encoder rotatable about an axis of a shaft; an actuator rotatable with the shaft and tiltable relative to the shaft; and a connector assembly interconnecting the actuator and the shaft to transmit rotational movement of the actuator to the shaft and permits tilting of the actuator. Each of the switches has a central axis and an upper surface to actuate the switch. A lever engages the upper surface at a first location on the central axis and pivotably engages actuator at a second location. The pivot axis is spaced from the first location a first vertical distance parallel to the central axis. The second location is spaced from the first location a second vertical distance parallel to the central axis 52. The first distance D1 is smaller than the second distance D2.
