Abstract
A system for sensing fluid conduit occlusion that reacts to occlusion force applied by changing the state of a switch only if a predetermined minimum force has been applied through the conduit. The system includes a contact member arm that cooperates with a force sensitive plunger to engage or separate a pair of contact members in response to application of a minimum force to the plunger. The plunger is positioned within a sensor gap through which the conduit extends.
