Abstract
A fluid sensor comprises a sensor housing (), a sensor package (), an actuator () and a switch (). The sensor package () is disposed within the sensor housing () and includes first and second screens and at least one sensing membrane. The sensing membrane is disposed between the first and second screens () and is adapted to expand when exposed to a predetermined quantity of a first predetermined fluid. The actuator () is disposed proximate the sensor package () within the sensor housing () and moveable between a first position and a second position through an intermediate position. The switch () is disposed proximate the actuator () and is operable between closed and open positions. When the actuator () is in the second position at least a portion of the actuator () depresses the switch () to control an-electrical, circuit connected therewith.
