*APPLIES TO ALL SWITCHES WITH TTL:
1. Selected position of the switch is controlled by TTL Logic 3. TTL LOGIC LEVEL: Low 0 to .8 VDC High 2.5 to 5.0 VDC
2. Switch requires only nominal +28 Vdc for coils (additional 5 Vdc is not required). 4. TTL LOGICD INPUT CURRENT: Low 0 mA High 1.6 mA max @ 3.85 VDC
