AC Coil DC Coil

Latching and Momentary Lever

Using the lever, operation can be checked without energizing the coil. The lever is color coded for AC and DC coils.

Latching Momentary

AC coil: Orange Red DC coil: Green Blue

In Normal Operation

Note: Turn off the power to the relay coil when using the latching

lever. After checking the operation, return the latching lever in the normal position.
