Title: Control button assembly for slider-type potentiometers and switches - has button with elastically deformable retaining clips which can be quickly assembled or de-mounted
Inventor: LOPEZ CLAUDE
IPC: H01C10/14
Filed: 1982-05-18
Abstract: The slider button arrangement is designed to overcome the difficulties often associated with fixing the button head to the slider shaft. The rear side of the button (10) is equipped with two pairs of projections (21,22,31,32) which have chamfered ends (23,24,33,34) and triangular bosses. The projections are elastically deformable. The separation of the inner projections (e) is designed to be equal to the diameter of the slider shaft (13) which is held rigidly between the inner projections during lateral movement. The sloping chamfered faces of the two pairs of projections are inclined in opposite directions. When the button is introduced to the narrow rectangular slot which defines the slider travel, the projections clip around the inner edge and hold the button rigidly by opposing elastic forces. The inner edges of the slot are bevelled to facilitate this movement. The button does not require for fixing by screws or glue. It can be assembled on the shaft and removed quickly.
