Turnstile with two common monitoring contacts

With this arrangement the rotation direction can be identified using the make and break sequence
of the switches.
Clockwise: If actuator A rotates clockwise it will close the exterior contact. A moment later, the actuator
A will move off the exterior contact and the contact will open again. As the turnstile
continues to rotate, actuator D will close the interior contact and a moment later, it will move
off the interior contact allowing it to open again.
