Reflowable circuit protection device

A circuit protection device comprising:

• a housing comprising:
• a first electrode;
• a second electrode;
• and
• an arming pin;
• a spring inside the housing, the spring comprising a first end and a second end, the first end of the spring being secured to an inside edge of the housing;
• a conductive slider inside the housing, the slider sliding from a first location to a second location within the housing such that at the first location the slider provides an electrical connection between the first and second electrodes, and at the second location the slider does not provide an electrical connection between the first and second electrodes, the slider comprising:
• a body portion having a pocket defined within at least a portion of the slider, the pocket receiving at least a portion of the second end of the spring, and the spring being held in tension between the pocket and the inside edge of the housing;
• and
• a fusible element attached to the slider, the fusible element having as an integral part a fusible link connected between the body portion of the slider and the arming pin, the fusible link holding the slider at the first location during a reflow process, and opening upon application of an arming current to the arming pin after the reflow process,
• wherein (i) the slider comprises at least one protrusion extending up from an upper surface of the slider, (ii) the fusible element comprises at least one opening matching the at least one protrusion, and (iii) the at least one opening receives the matching at least one protrusion.
