Abstract
A plug-in shaft is provided for insertion into a noncircular opening provided in a driver and integral hub of a variable resistance control providing a means to alter the rotational torque of the control. Integral with the hub is a dish shaped abuttment section and a driver engagement portion of the shaft supports a plurality of nubbins engaging the abuttment section of the hub upon insertion of the shaft into the noncircular opening to secure the shaft in a predetermined position within the slot. The nubbins engaging the dish shaped abuttment section provide radial pressure on the hub and restrain the axial movement of the shaft within the noncircular opening. An alignment portion of the shaft contiguous with the driver engagement portion rigidly prealigns the shaft in an upright and intact manner within the noncircular opening before the engagement portion and nubbins engage the noncircular opening.
