Claims (1)
圧を画定するダイヤフラムプレートと、前記大気
圧室内に設けられた固定接点と、前記負圧室内の
負圧に応ずる前記ダイヤフラムプレートの移動に
応じて、前記固定接点と接触、離間する可動接点
を備え、前記大気圧室と大気とをフイルターを介
して連通させた圧力スイツチ装置において、前記
フイルターを揆水性の樹脂材にて形成した圧力ス
イツチ装置。 a diaphragm plate that is movably arranged within the body and defines a negative pressure chamber and atmospheric pressure; a fixed contact provided in the atmospheric pressure chamber; and a diaphragm plate that moves in response to the negative pressure in the negative pressure chamber. A pressure switch device comprising a movable contact that contacts and separates from the fixed contact and communicates the atmospheric pressure chamber with the atmosphere through a filter, wherein the filter is formed of a water-repellent resin material. .
