Touch sensor assembly and refrigerator door including same

A touch sensor assembly comprising:

• a sensor housing positioned at a rear surface of an exterior member in which a touch input region is marked on a front surface;
• a sensor printed circuit board (PCB) provided in the sensor housing, the sensor PCB including a first surface facing the rear surface of the exterior member and a second surface opposite the first surface;
• a touch sensor mounted on the first surface and configured to sense a touch input at the touch input region;
• an elastic member pressed against the second surface of the sensor PCB and pushing the touch sensor toward the rear surface of the exterior member;
• and,
• an accommodation recess formed in an inner surface of the sensor housing and providing an installation position of the elastic member,
• wherein the elastic member includes:
• an extension pressed against a bottom of the accommodation recess;
• and
• a pair of support legs extending from both ends of the extension,
• wherein ends of the pair of support legs are pressed against a rear surface of the sensor PCB, and the elastic member is formed of a silicon having elasticity, or a synthetic rubber and a resin material having elasticity similar to the elasticity of the silicone.
