There are two drive coils inside the switch which are used individually to set the switch in each of the two possible optical states to change the state of the switch, apply a 5 VDC drive pulse of approximately 20 m sec or longer on the electrical drive pins as indicated in the table below. Once the switch has been moved to the new position it will remain there until a drive pulse appears on the drive coil for the other path. Typical operating current is 40 mA during switching.

There are two sets of single pole double throw contacts which are also operated by the switch. These can be used to sense the position of the switch or to operate other circuits based on the switch path chosen.
