A switchable jumper that securely switches PCB track signals with a
positive contact action.
Supplied in units of 1 through 16 poles they provide an alternative
to manually inserted jumpers. Available with 2-position (SPST)
(JSA4), 2-position (SPDT) (JSC4) and 3-position (CENTER-OFF) (JSK9)
switch actions. All contacts can be supplied in ganged pairs. (See
ordering code).
Longer units (up to 16 poles) save loading time on production. On
development they can be cut to achieve any combination
required to provide flexible switching with the least routing on a
PCB.
Options available include 2 pole ganged style actuators of
different colors in the EIA range and a mixture of colors for
actuators in multiple way versions and actuator numbering.
Reliable switching of the gold over nickel plated phosphor bronze
contacts is assured with the 4 point wiping contact design. The
contacts never rub over any plastic part and every one is tested.
The positive detent action ensures good shock resistance and the
deep ‘V’ slots securely locate any operating probe.
Jumper-Switch™has been designed for use on hand or flow
soldered and washed PCBs. The tight pin fit prevents any wicking.
Users should evaluate that their particular processes are
compatible with the unsealed contact design concept.
