Abstract
A blade closing detector for an electric power switch includes a blade closing detector and an electronic or visual indicator. A first type of detector uses a gravity switch and a magnetic pickup to detect proper engagement between the blade and the switch. A second type of detector uses a sliding latch with a visual indicator rod to provide a visual indication of proper engagement of the blade within the jaws. A third type of detector uses a magnetic switch with a pivot arm and a dome shaped visual indicator. These detectors may be deployed individually or in combination and may be augmented with communication equipment to transmit switch status to a remote location. It will be understood that specific embodiments may include a variety of features in different combinations, as desired by different users.
