System and method for air pressure electric switch pressure adjustment |
摘要 |
A system for air pressure electric switch adjustment comprises a frame. A pressure port is mounted to the frame for connection to a source of fluid under pressure to be monitored. An actuator is movably mounted relative to the frame responsive to fluid pressure at the pressure port. A switch includes a fixed contact and a movable contact. The fixed contact is fixedly mounted relative to the frame. A differential mechanism comprising a pair of linked levers is hingedly mounted to the frame. One of the linked levers is driven by the actuator. The other lever carries the movable contact. A snap spring links the two levers so that the other lever is normally in a first position with the switch in a normal state. The other lever is toggled responsive to pivotal movement of the one lever by the snap spring to a second position with the switch in an actuated state. A switch adjustment mechanism is operatively mounted to the frame for varying the first position of the other lever relative to the one lever to vary actuation pressure.
