Claim:
1. An actuation system for a switch assembly having at least one switch, the actuation system comprising: a linear actuator drivable for actuating the at least one switch; a handle for selectively driving the linear actuator, wherein the handle is operable in a first state in which the handle is coupled to the linear actuator such that turning the handle does not drive the linear actuator, and a second state in which the handle is coupled to the linear actuator such that turning the handle drives the linear actuator; a shaft coupled between the linear actuator and the handle, wherein the handle turns relative to the shaft in the first state and rotates the shaft when turned in the second state; wherein the handle is coupled to the shaft for keyed interaction with the shaft; wherein the handle comprises a spring and a housing displaceable along the shaft against a bias of the spring to enable the keyed interaction of the handle with the shaft; and a lug coupled to the shaft, wherein the lug defines a key and the housing defines a keyhole such that the key of the lug is insertable into the keyhole of the housing to enable the keyed interaction of the handle with the shaft; wherein the housing receives a locking device in a manner that inhibits the housing from being displaced along the shaft to prevent the keyed interaction.
