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°to effect a corresponding range of rectilinear reciprocation of the contact.

In an automatic ice maker having a water valve and rotary switch means for controlling operation of the water valve, a manually adjustable contact structure associated with said rotary switch means for varying the time of operation of said water valve, said contact structure comprising: an electrical contact; support means supporting said contact for reciprocal rectilinear positioning relative to said switch means, said support means having a thread engagement portion; a screw having a threaded shank threadedly engaging said thread engagement portion of the support means, and an end portion having a noncircular cross section; means for mounting said screw for axially fixed rotation about the axis of said shank; a housing for said structure having a wall provided with an opening aligned with said screw end portion; and a control knob having a manually operable portion, a connecting portion projecting from said manually operable portion and having a socket complementary to said screw end portion, and knob mounting means rotatably mounting said knob to said housing wall in said opening with said screw end axially movably and rotatively fixedly received in said socket for rotation of said screw as an incident of rotation of said manually operable portion, whereby rotation of said control knob effects linear movement of said contact in engagement with said rotary switch means, said contact and rotary switch means comprising cooperating means for varying the time of operation of the water valve as a function of the position of said contact relative to said rotary switch means.
