摘要： A clutch mechanism for a pushbutton tuner effects operative driving engagement between a depressible adjusting shaft and a tuning shaft, both axially aligned and rotatable in a housing. The adjusting shaft is accessible externally of the housing and has a housing-enclosed part which is tubular in shape with spaced longitudinally extending grooves in the tube walls. A springurged tubular connecting member having spaced protrusions is received within the adjusting member tube part, with the protrusions riding within the grooves, and at a base thereof the tube bore walls are contoured to mate with projections on the tuning shaft upon alignment therewith. A caplike member encloses the tube part open end, and it is spring urged to move the clutch mechanism to its undepressed condition. Upon depression of the adjusting shaft the connecting member is moved toward the projections, and if the projections and contoured walls are not aligned, the connecting member is forced to slide within the tube, compressing the spring active thereon. Upon rotation of the adjusting shaft, the projections and the contoured walls align, and the spring acts on the connecting member so that the projections and walls come into operative driving engagement. Continued rotation of the adjusting shaft in either direction effects adjustment of the tuning shaft without lost motion. Holding means maintains the adjusting shaft in its depressed condition, and disengagement of that holding means permits the second spring to return the adjusting shaft to its undepressed condition.

摘要： An actuator for a switch and/or indicator comprises a shaft rotatably passing through a wall and having a flexible nodal switching arm attached thereto, the shaft being operatively connected to a switch and/or indicator or the like. The wall through which the shaft passes is provided with a plurality of spaced nodes projecting therefrom into the path of movement of the nodal switching arm past which said nodal arm can move as a result of the bending of said arm, and is further provided with stop members engageable with said arm beyond said nodes. The construction is exceptionally well adapted for use in a multiband tuning device provided with a tuning shaft, the shaft of this assembly being rotatably mounted on the tuning shaft and being operatively connected both to a band-selection switch and to an indicator.
