Jumper-Switch A switchable jumper on 0.1 pitch that securely switches PCB Drop in replacement for jumpers. track signals with a positive contact action. Secured in the ON or OFF setting. Supplied in units of 1 thru 16 poles they provide an alternative to jumpers without the need for parking pins on the PCB or 0.1 mounting pitch. exposed bare pins and are available with ON/OFF (JSA4), CHANGEOVER (JSC4), and CENTRE-OFF (JSK9) switch 1 thru 16 ON/OFF, CHANGEOVER and actions. All contacts can be supplied in ganged pairs. (See ordering code). CENTRE-OFF contacts. Longer units (up to 16 poles) save loading time on production. Ganged pairs of contacts option. On development they can be cut with a modelling knife to achieve any combination required to provide flexible switching Hard gold plated wiping contacts. with the least routing on a PCB. If you have a volume requirement for a Options available include 2 pole ganged style, sliders of different colours in the EIA range and a mixture of colours for sliders in product variant not shown on this sheet multiple way versions and slider numbering. please contact us. 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 before despatch. 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.
