Double solenoid mechanism. Charlie's tips: Can be activated with a circuit track, as well as a switch (like the 72720). Double throw can be used for a signal (red-green). Single throw for supplying track power to stop track section. On the first diagram image you see two of the block of 4 connectors used as one of the "on/off" switches. You can use the second set of two connectors on that block of 4 for another section of track (for example fed by a different transformer). The block of three connectors is the double throw switch.
