Closed Top Shunt at 0.200" Pitch — Not a Standard 2.54mm Jumper
The 65771-002LF is a 2-position closed top shunt from the Mini-Jump™ series, with a 0.200" (5.08mm) pitch — twice the spacing of the common 0.100" (2.54mm) shunt. This means it mates only with headers or pin strips on 5.08mm centers, not the standard 2.54mm grid found on most breadboards or prototype boards. The closed top design protects the contact beams from accidental shorting or debris ingress.
The polyester housing and tin plating meet the directive requirements for lead-free assembly.
