ABSTRACT:
A mechanical sensor is placed beside the return run of the steps on an escalator or moving walk, The sensor is biased toward the steps so as to bear against each step passing thereby. If a step in the series is missing from its normal position, the sensor will move in the direction of the step run and will open a switch in the escalator power circuit thereby shutting off power to the escalator. The switch can only be manually reset by a mechanic from a location which is closed off to the public.
