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.

A key structure including a carrier, a keycap, a lifting member, and an elastic member is provided. The carrier includes a carrier body and multiple positioning hooks. The carrier body has multiple vias, and the positioning hooks are respectively disposed corresponding to the vias. Orthographic projection of each of the positioning hooks falls in the corresponding via. Each of the positioning hooks includes a first positioning portion and a second positioning portion respectively connected to two inner wall surfaces in the corresponding via. The keycap is disposed above the carrier body. The lifting member is disposed between the carrier body and the keycap. One end of the lifting member is connected to the keycap, and an other end of the lifting member is connected to the positioning hooks. The elastic member is disposed between the carrier body and the keycap.

A photoelectrical type of mechanical switch, wherein a chute is provided on the bracket; the ram upper end is provided with a protruding strip arranged in the chute which can freely move along the chute; when the bracket moves up and down, the protruding strip is restricted by the chute and drives the ram to rotate by itself. Adoption of the independent sound optical path structure enables its exhibition of more obvious key-pressing stage sense and key-pressing sound when pressing the press shaft, and can realize good “ON/OFF” function of optical path.

A mechanical computer keyboard including a plurality of keys and an input/output (i/o) interface for output of registration of pressing one or more of the plurality of keys. Each key includes a keycap, a key switch including a stem, a key registration unit for registering a keystroke, and a spring for forcing the keycap in a neutral release position and providing a perceptible increase in pressing force. The keyboard further includes an analog-to-digital converter and the keys include a distance sensor unit for determining a travel distance of the pushing-down of the keycap by measuring a complex electrical impedance corresponding to the travel distance of the pushing-down the keycap, wherein the analog-to-digital converter is configured to convert the complex electrical impedance to a digital input signal including a digitalized keystroke travel distance for outputting of the digital input signal by the i/o interface towards the computer.
