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. A vent hole that communicates with the outside part is arranged in the outside part of the switch body so that one end is close to the open end of the vent hole, and water droplets adhering to the open end of the vent hole are removed by water surface tension or capillary action. A diaphragm switch comprising a guide rib that spreads the air from the open end of the vent hole to the surrounding area.
