Abstract
An elevator governor includes a selectively powered switch () that is activated when an elevator car moves at a speed that exceeds a selected limit. The speed limit is lower than normally expected car speeds during normal elevator operation. The switch () is activated by a moving member () that moves into a switch-activation position responsive to movement of a rotating member () that corresponds to movement of an elevator car. The arrangement allows for a primary governor to prevent elevator speeds from exceeding a first selected limit and a secondary governor to prevent elevator speeds from exceeding a second, lower limit.
