Second, the area below the button is not rigid and so it gives way when pressure is applied to the button. The top and bottom casings provide a casing structure which includes two detents. One detent is for locking the device with the connector in the extended position, and one detent for locking the device with the connector retracted in the in position. This allows for just one press of the extended portion of the positioning device to unlock it from its present position. When the device reaches its new position it will automatically lock.
