| Pin | Signal | Type | Function & connection |
|---|---|---|---|
| 1 | Contact terminal 1 | Toggle: end lug 1 (C&K) or terminal 3 (E-Switch). Rocker: one tab. DIP switch: pin 1, the square pad. Panel switches reach the board on header pad 1.Connection guidanceConnect to the supply or signal being switched. A switch has no polarity; respect the voltage and current rating of the switch chosen. | |
| 2 | Contact terminal 2 | Toggle: terminal 2, the centre (common) one. Rocker: the other tab. DIP switch: pin 2. Header pad 2.Connection guidanceConnect to the load, or to the input being configured. Closed: 10 mΩ C&K toggle, 20 mΩ / 10 mΩ / 50 mΩ E-Switch 200 / 100 / ST4, 100 mΩ rocker, 50 mΩ DIP (maximum, initial). |
