ABSTRACT:
The problem of providing a simple, small, lightweight and reliable flow responsive switch mechanism (32) in a fan structure, such as for aerospace applications, is solved by providing a housing (12) defining a fan involute (22). An impeller (18, 20) is mounted in the housing for forcing air through the fan involute. A vane (34) is disposed directly in the fan involute, rotatably mounted on the housing, for rotation in response to air flow through the fan involute. An electrical switch (52) is mounted on the housing and is operatively associated with the vane for altering the state of the switch in response to air flow through the fan involute from the impeller.
