Abstract
PURPOSE: To make it easy to adjust a blockade detecting apparatus which is operated by negative pressure source, and to make it possible to operate accurately the apparatus.
CONSTITUTION: A working member 3 partitions a room into a negative pressure chamber 9 and a receiving chamber 11, said working member 3 consisting of a diaphragm 13, a retainer 14 and a press pin 15, said room being composed of an upper casing 1 and a lower casing 2 having an inlet part 7. A microswitch 4 having hysteresis character is arranged in the receiving chamber 11. The microswitch 4 is switched on or off by the movement of the working member 3.
