A switching device has a cover including: a hollow content area housing a plurality of connectors; one or more openings designed to allow passage of one or more conductors; and one or more reflective agents mounted on the cover such that changing a physical location of an entirety of the cover with respect to an enclosure of an electronic device changes a location of the one or more reflective agents. A sensor is configured to sense the one or more reflective agents and output an electrical signal depending on the location of the sensed one or more reflective agents mounted on the cover. The sensor is positioned outside of the hollow content area of the cover. A controller is configured to change a state of the electronic device according to the output electrical signal of the sensor. The cover is mounted on an exterior surface of the enclosure.

A touchless trigger apparatus is touchless button, comprising a photon-gate side, a photon-gate distal side more than 1 cm (11.0 in) and less than 30 cm (11.0 in) across the photon-gate opening, to the photon-gate side. An electro-optical sensor is connected to the photon-gate side. An ASIC controller is connected to the output of the electro-optical sensor. Lastly a button face is within the opening of the photon gate. Alternatively, a touchless trigger apparatus is a touchless pushbutton, or a touchless switch. Any person or primate trained to use a button, pushbutton or switch could intuitively learn to use a touchless trigger apparatus due to its recognizable combination of elements and low-latency feedback before touching the button, the pushbutton or the switch.

An optical keyswitch includes a keycap, a supporting mechanism having a protrusion disposed under the keycap to support the keycap to move downward or upward, and a switch module including a circuit board, an emitter, and a receiver. The emitter and the receiver are electrically connected to the circuit board. The emitter emits an optical signal to the receiver. When the keycap is not pressed, the receiver receives the optical signal of a first intensity. When the keycap is pressed, the protrusion moves along with the keycap, and the protrusion changes the optical signal received by the receiver to have a second intensity different from the first intensity, so the switch module is triggered to generate a triggering signal.
