Abstract: An indicator switch assembly for filters wherein a piston responsive to differential pressures within the filter housing is movable to indicate the differential between said pressures and to move a finger member between a pair of closed switch arms to separate the same and break the circuit therebetween, continued movement of said finger member being effective to close at least one of said switch arms with a third switch arm to create a circuit therebetween.
Abstract translation: 一种用于过滤器的指示器开关组件，其中响应于过滤器壳体内的压差的活塞可移动以指示所述压力之间的差异，并且使手指构件在一对闭合的开关臂之间移动以将其分开并在其间断开电路，继续 所述指状构件的运动有效地用第三开关臂关闭所述开关臂中的至少一个，以在它们之间产生电路。
