ABSTRACT:
A floor selector comprises a first and a second switch on an elevator car, a vertical array of first switch actuators each disposed between each pair of adjacent floors in a hoistway, and another vertical array of second switch actuators located below the first actuators in the hoistway. When the first switch engages each of the first actuators, a synchronized floor is renewed by adding one floor to the preceding synchronized floor read out from an RAM by a micro-processor and written into the RAM. When the second switch engages each of the second actuators, an advanced floor in advance of the synchronized floor is renewed by adding two floors to the preceding advanced floor read out from the RAM by the micro-processor and written into the RAM.
