| ● ELECTRICAL / COMMON SPECIFICATIONS | |
| Switch Rating | SPST, 20 VA. |
| Lead Wire Gauge | No. 22 AWG. |
| Mounting Attitude | Horizontal. |
| Switch Operation | Depending on mounting position, the float can rise or lower with liquid level. Rotating the switch 180° changes operation between Normally Open and Normally Closed. When the switch is mounted so the float lowers with liquid level, the switch is N.O.; when mounted so the float rises with liquid level, the switch is N.C. |
