1. A fluid flow switch sensing device comprising:
- an enclosure;
a switch disposed within the enclosure;
a bracket pivotally mounted to a wall of the enclosure, wherein pivotal movement of the bracket activates the switch to a desired switch function, the bracket including a button extension;
a paddle arm coupled to the bracket for causing pivotal movement of the bracket in response to fluid flow in a conduit;
a button extending through the enclosure and cooperatively associated with the bracket for external manual actuation and deactuation of the fluid flow switch sensing device, the button including an end which engages the button extension when the button is pressed; and
a hollow body affixed to a lower surface of the enclosure, the body enabling the device to be threadedly installed to the conduit through which a fluid flows, the flow of the fluid being monitored by the device;
wherein a space is maintained between the end of the button and the button engagement extension when the button is in a rest position.
