ITW ERG Sub-Miniature Jumper Switches
JS Series
Sub-Miniature Gold Plated Jumper DIL Switches
A switchable jumper on 2.54mm (0.1") pitch that securely switches PCB track signals with a positive contact action. Supplied in units of 1 thru 16 poles they provide an alternative to jumpers without the need for ‘parking pins’ on the PCB or exposed bare pins and are available with ON/OFF (JSA4), CHANGEOVER (JSC4), and CENTRE-OFF (JSK9) switch actions. All contacts can be supplied in ganged pairs. (See ordering code).
Features
- Drop in replacement for jumpers
- Secured in the ON or OFF setting
- 0.1" mounting pitch.
- 1 thru 16 ON/OFF, CHANGEOVER and CENTRE-OFF contacts
- Ganged pairs of contacts option
- Hard gold plated wiping contacts
