Working Principle:
    |
An inlet and An outlet: Normally Closed: When the coil is energized, 2 leads to 1, 1 and 3 off. When the coil is powered off, 2 and 1 are closed and 1 leads to 3. Normally open: when the coil is energized, 3 and 1 off, 1 to 2. When the coil is powered off, 3 leads to 1, 1 and 2 off. |
One in two out: When the coil is energized, 1 leads to 2, 1 and 3 off. When the coil is powered off, 1 and 2 are off and 1 leads to 3. | |
Two in one out: When the coil is energized, 2 leads to 1, 3 and 1 off. When the coil is broken, 2 and 1 are closed and 3 leads to 1. |
