Claim Text:
1. A three-function reflowable circuit protection device comprising: a substrate comprising a first electrode, a second electrode, and a heater element, the heater element receiving an activation control current; a sliding contact positioned on the substrate at a first location and having a cantilevered portion extending into an opening in the substrate for restricting movement of the sliding contact to a linear path, wherein at the first location the sliding contact is connected to, and provides a conductive path between, the first electrode, second electrode, and the heater element via a sensing element; a spring element biasing the sliding contact along the linear path to a second location upon loss of resilience of the sensing element, wherein at the second location the sliding contact does not provide a conductive path between any of the first electrode, second electrode, and the heater element, and a restraining element securing the sliding contact at the first location during a reflow process, wherein the sensing element loses resilience upon detection of any one of the following activation conditions: wherein application of an arming current through the restraining element causes the restraining element to break and place the circuit protection device in an armed state.
