技術說明

本發明揭示了一種慣性開關，包括相互堆疊的底板和蓋板，所述底板上設有液體儲存腔、感測腔以及導通其間的流道，所述液體儲存腔內密封有定量之工作流體；所述感測腔內設有延伸至慣性開關外部之感應電極。本發明利用液態材料作為慣性感測之檢測體，並藉由流道寬度、深度及角度設計，當液態材料經過流道延時後進入感測腔時，可藉由感測電極透過電阻值或電容值變化，得到訊號以進行開關啟動操作，結構簡單，成本低廉。 The present invention discloses an inertia switch, which includes a stack of a base plate and a base cover. Said base plate provided inside a liquid storage chamber and a sensing chamber communicating with a liquid storage chamber. Said liquid storage chamber contains working fluid, and the sensing chamber equipped with a sensing electrode extends to and connected to external devices that connected with the inertia switch. The present invention utilizes the electricity-conductive liquid as inertia sensing’s detecting element, and by the width, depth and angle of the flow channel design, when the time delay mechanism as liquid material through the flow channel into the storage chamber, a sensing signal is obtained by the sensing electrodes through a change of a resistance value or a capacitance value. Thereby gives a signal to the switch and starts an operation. The inertia switch in accordance with present invention is of simple structure and low cost.
