KW4A rice cooker micro switch long lever 10T85 10T105 25T125
Model: KW4A

Internal configuration drawing


KW4A miniature micro switch has wide range of applications in rice cooker,microwave oven and ovens. It plays significant control and protection roles in these devices. Mainly include timing control, temperature control and water lever control. For example, rice cookers generally have a timer function that allows you to predetermine the cooking time. Small micro switches are used to detect the position of mechanical rotating parts in rice cookers. Gears and triggers are usually used to control the timing function.
