The invention is a retrofit device for converting a standard switch to a smart switch. The retrofit device taps into an existing switch electrical terminal via one or more sliding arms with electrical contacts. The electrical contacts interface with the terminals, thus providing a control circuit to intervene or interrupt the existing switch function and allow a control system to control the electrical circuit the existing switch serves.

A toggle button assembly for a human-machine interface (HMI). The toggle button assembly includes a circuit board. A first switch and a second switch are mounted to the circuit board. A toggle body is rotatable about a toggle body rotation axis. A first switch actuator is between the toggle body and the first switch, and a second switch actuator is between the toggle body and the second switch. Upon actuation of the toggle body from a center position to a first position, the toggle body rotates about the toggle body rotation axis and presses the first switch actuator against the first switch to actuate the first switch. Upon actuation of the toggle body from the center position to a second position, the toggle body rotates about the toggle body rotation axis and presses the second switch actuator against the second switch to actuate the second switch.

A switch structure used for switching on or off an electronic system is provided. The switch structure includes a base, a switch body pivoted to the base, a first electrode connected and moved along with the switch body, a second electrode disposed on the based and corresponds to the first electrode, a torsion assembly, and a power source. The first electrode and the second electrode are electrically connected to the electronic system, respectively. The torsion assembly is connected to and drives the switch body, so as to drive the first electrode and the second electrode to switch between a conductive state and a non-conductive state. The power source is connected to the torsion assembly, and the power source provides a torsion to the switch body via the torsion assembly in an automatic state so as to switch the switch structure between the conductive state and the non-conductive state.
