McMillan (ed) ''Process/Industrial Instruments and Controls Handbook (5th Edition)'' (McGraw Hill, 1999) ISBN 0-07-012582-1 page 7.26〕 The film of oxidation occurs often in areas with high humidity. Providing a sufficient amount of wetting current is a crucial step in designing systems that use delicate switches with small contact pressure as sensor inputs. Failing to do this might result in switches remaining electrically "open" when pressed, due to contact oxidation. ==Snubber capacitor== In some low voltage applications where switching current is below the manufacturer's wetting current specification, a capacitor discharge method may be employed by placing a small snubber capacitor across the switch contacts to boost the current through contact surface upon contact closure.〔The Case of the Intermittent Relay, Design News, Stewart, Anthony, 2011〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Wetting current」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
