Connection device for operating stations of computer - connects accordance with any cct. and varies as required

摘要

The connecting device comprises electronic switching means which establish the required connections under control of operating elements generating specific signals for each connection pattern. The operating elements consist of a light source for selective illumination of optoelectronic switches. A removable perforated mask is provided between the light source and the switches. It is perforated in accordance with a certain code. The switching means are directly connected by the optoelectronic switches to the required points and the switches are devices with photosensitive SC devices, such as photodiodes or phototransistors. The danger of poor contacts is avoided and information is conveyed with high speed as a consequence of the suppression of parasitic capacitances.
