水管との間に設置される警報スイッチにおいて、ばねに
て上方に付勢された負圧移動体を内嵌し、ベローフラム
により気密封止されるシリンダーと、マイクロスイッチ
を丙蔵した作動部とから成り、シリンダーの下部に通気
用の連通孔を形成し、前記負圧移動体の摺動により引き
下げられマイクイロスイッチを作動させるスイッチ作動
棒を負圧移動体に設けた筒体に摺動可能に挿入し、ばね
にて上方に付勢したことを特徴とする負圧スイッチ。In the alarm switch installed between the automatic alarm valve installed in the sprinkler piping on each floor and the drain pipe, a negative pressure moving body biased upward by a spring is fitted inside and hermetically sealed by a bellows frame. It consists of a cylinder and an actuating part containing a microswitch. A communication hole for ventilation is formed at the bottom of the cylinder, and a switch actuating rod that is pulled down by the sliding of the negative pressure moving body and actuates the microswitch is connected to the cylinder. A negative pressure switch characterized by being slidably inserted into a cylindrical body provided on a pressure moving body and biased upward by a spring.
