DOOR SWITCH FOR REFRIGERATOR

摘要

A door switch for a refrigerator is provided to drop impurities through an opening groove between an external bracket and an inner casing by forming buttons for operating regulation switches in a double structure, thereby preventing infiltration of moisture or soap bubbles into the inner casing where a regulation switch is installed. An inner casing(20) is installed inside a cabinet. External buttons(41,45) are installed in the cabinet, movably toward the inner casing, wherein a part of each external button is exposed out of the cabinet. Internal buttons(51,55) are movably installed in the inner casing to interwork with the external buttons. Regulation switches(61,65) are installed in the inner casing, to be operated by the internal buttons.
