Abstract
Abstract An actuator mechanism for a switch or a circuit breaker comprising a rocker handle having a cavity for housing an indicator lamp. The lamp is energized when the rocker handle, and consequently the main contacts of the switch or circuit breaker, are in a first position, and de-energized when the rocker handle and the main contacts are in a second position. The lamp is located beneath a translucent cover which may be marked with suitable indicia to display the condition of the main contacts. The lamp is connected in series with a power source through a pair of rocker contacts carried by the rocker handle and pivotable therewith. The rocker contacts are movable into or out of engagement with a pair of stationary contacts which are supported adjacent the rocker handle, the stationary contacts and the support means therefor being located in the space between the top surface of the switch or circuit breaker case and the lower wall of the panel to which the case is mounted. When the stationary contacts are in engagement with the rocker contacts, a conductive path is completed from the power source through the indicator lamp to illuminate the rocker handle, thereby indicating the condition of the main contacts.
