Abstract: A device for the automatic and momentary electrical connection of the wires of a cable with the circuit of a memory. A sensor connects each wire of the cable with a telescopic tip and an electronic chip which connects the telescopic tips to a memory. As a button provided on the cover of the sensor is depressed, the telescopic tips pierce through a protecting film on the face of the electronic chip and provide electrical contact between the cable and the memory. The sensor and electronic chip each have a bevel gear, the teeth of which position the sensor relative to the electronic chip so that each engages an electrical contact on the surface of the electronic chip. An electronic circuit connected with the cable senses the angular position of each of the telescopic tips with reference to the electrical contacts. This device provides a momentary electrical contact with the electronic chip to read a memory or store data therein.
