Switching device

In a switching device comprising a control shaft rotatable from a neutral position to and beyond a switch actuating position, centering means coupled to said control shaft for resiliently biasing the same to said neutral position, a switch mechanism having a resiliently depressible actuating member, and switch actuating means for depressing said actuating member in response to rotation of said control shaft to said switch actuating position;

• the improvement wherein said switch actuating means comprises a cam coupled to said control shaft and including an adjustable cam finger extending generally radially with respect to the axis of said control shaft having a free end radially distant from said control shaft and a base end coupled to said control shaft, and a fixed cam finger disposed circumferentially behind said adjustable cam finger;
• a cam follower slidably contacting said cam to deflect in response to rotation of said cam, said free end of said adjustable finger contacting said cam follower to move the same when said control shaft is rotated to said switch actuating position and said fixed cam finger contacting said cam follower when said control shaft is rotated beyond said switch actuating position;
• and linkage means coupled with said cam follower for depressing the actuating member of said switch mechanism when said control shaft has rotated to or beyond its switch actuating position.

In a switching device comprising a control shaft rotatable clockwise from a neutral position to and beyond a first switch actuating position and counterclockwise from said neutral position to and beyond a second switch actuating position, centering means coupled to said control shaft for resiliently biasing the same to said neutral position, first and second switch mechanisms each having a resiliently depressible actuating member and positioned with their respective actuating members facing one another, and switch actuating means for depressing the actuating member of said first and second switch mechanisms in response to rotation of said control shift to its first and second switch actuating positions, respectively;

• the improvement wherein said switch actuating means comprises a cam arrangement coupled to said control shaft and including first and second cam fingers each extending generally radially with respect to the axis of said control shaft and having a free end radially remote from said control shaft and a base end coupled to said control shaft;
• first and second cam followers slidably contacting at least the free ends of said first and second cam fingers, respectively, to deflect in response to rotation of said cam arrangement when said control shaft is rotated to said first switch actuating position and to said second switch actuating position respectively;
• and linkage means coupled to said first and second cam followers for depressing the respective actuating member of said first and second switch mechanisms when said control shaft has rotated to or beyond its first and second switch actuating positions, respectively.

In a switching device comprising a control shaft rotatable clockwise from a neutral position to and beyond a first switch actuating position and counterclockwise from said neutral position to and beyond a second switch actuating position, centering means for resiliently biasing said control shaft to said neutral position;

• first and second switch mechanisms each having a resiliently depressible actuating member, and switch actuating means for depressing the actuating member of said first and second switch mechanisms in response to rotation of said control shaft to its first and second switch acutating positions, respectively;
• the improvement wherein said switch actuating means comprises a first cam follower and a second cam follower;
• linkage means coupled to said first and second cam followers for depressing the actuating member of a respective one of said first and second switch mechanisms in response to deflection of said first and second cam followers;
• and a cam arrangement coupled to said control shaft and including a first cam plate and a second cam plate arranged axially atop one another on said control shaft, each of said first and second cam plates having camming means thereon for slidably contacting a respective one of said cam followers, each said camming means including a cam finger extending generally radially with respect to said control shaft, said cam plates having radial slots therein adjacent said cam finger adapted to receive an adjusting tool for bending said cam finger to adjust the circumferential position at which the latter contacts the respective cam follower, and at least one of said cam plates having a cutout formed therein to permit access for said adjusting tool to the slots and cam finger of the other of said cam plates.
