ムスイツチ。 A switch body has a pressure chamber and a switch chamber separated by a diaphragm, and a switch that turns on and off in response to displacement of the diaphragm is disposed in the switch chamber, wherein the switch chamber and the switch body are connected to each other. It is equipped with a ventilation hole that communicates with the outside part, and a protrusion that is disposed so that its tip is close to the open end of the ventilation hole, and the water droplets attached to the open end of the ventilation hole are absorbed by the surface tension of the water. Alternatively, the diaphragm switch is characterized in that it is attached to the protrusion by capillary action and removed from the open end of the vent.
