ABSTRACT:
An automatic ice maker structure having a water valve and rotary switch for controlling operation of the water valve. A manually adjustable switch contact structure is associated with the rotary switch for varying the time of operation of the water valve and thereby adjusting the size of ice bodies produced in the ice maker. The switch contact structure includes a support supporting the contact for reciprocal rectilinear positioning. The support has a thread engagement portion and a screw is provided having a shank threadedly engaging the portion of the support. A control knob is rotatively mounted on a wall of the housing of the control. The control knob is connected to a noncircular end portion of the screw for rotatively fixed, axially movable association therewith. The control knob is snap-fitted to the housing wall to engage the screw end. The control knob is rotatable over approximately 350.degree. to effect a corresponding range of rectilinear reciprocation of the contact.
