The present invention provides a retrofit actuator that can be fitted interchangeably to either a toggle switch or a rocker switch and which mimics both the up and down action required to operate a toggle switch and the pushing force required to operate a rocker switch, the retrofit actuator capable of being operated either directly by pressing an on/off button on the switch actuator itself or remotely by sending a signal from a remote control or other sender unit such as a passive infra red detector or a programmable central sender unit that can control one or more switch actuators from a remote location.
