<p>A body pressure sensing switch includes a hard elastic plate that has a hole with an opened upper surface, a pressure switch that is accommodated in the hole, and a fluid accommodating unit that is disposed on the hole with a portion larger than the diameter of the hole and accommodates a fluid. When pressure is added to the fluid accommodating unit, the fluid accommodating unit is deformed so as to cut into the hole, and an on/off signal is detected by the pressure switch.</p> |
