ABSTRACT:
An improved keyswitch circuit for an escalator or moving walkway senses the normal (center or lateral) position of the keyswitch and, if the keyswitch does not return to its normal position after a selected event such as a selected normal starting interval, then the safety circuit is opened and the escalator or moving walk is stopped; the escalator or moving walkway can be restarted only after first returning the keyswitch to its normal position.
