ABSTRACT:
A removable interlock spacer is disposed between the rear face of a control knob and the face of a control panel of a cooking device, such as a stove or a barbecue grill, to prevent the control knob from being pushed in far enough to activate the associated cooking element(s). The push-in-and-turn type switches used in such devices require that the control knob be pushed in before the switch can be moved from its off position. The interlock spacer is of sufficient thickness to prevent the control knob from being pushed in far enough to allow the switch to be moved from its off position. Thus, the cooking element cannot be activated with the interlock spacer in position. When the cooking device is to be used, the interlock spacer may be removed and the switch will operate normally. Thereafter, when cooking is complete, the interlock spacer is re-installed so that young children and the like will not inadvertently create a hazard to themselves and others.
