ACTUATOR ASSEMBLY FOR ELECTRICAL SWITCHES HOUSED IN AN ENCLOSURE

An actuator assembly for actuating an electrical switch housed in sealed electrical enclosure is disclosed. The actuator assembly includes a handle assembly including a handle positioned on an exterior of a cover of the sealed enclosure, a trip bracket positioned within the sealed enclosure and a shaft connecting the handle to the trip bracket. A slider actuator is slidably mounted over an electrical switch positioned within the enclosure and operatively associated with or coupled to a toggle of the electrical switch. The slider actuator has a drive link which is adapted to engage the trip bracket such that rotation of the handle activates the drive link which causes linear movement of the slider actuator to move the electrical switch between on and off positions. The use of the slider actuator allows a higher density of electrical switches to be stacked within the sealed enclosure.
