A multi-contact data module for a connection matrix having an input channel and a plurality of output channels, said data module comprising at least one switching body means defining a hollow internal cavity, contact pins for establishing electrical connections to the input channel and the plurality of output channels of the connection matrix, said contact pins extending into said hollow internal cavity of said switching body means. Movable contact means are disposed within said hollow internal cavity of said switching body means for cooperation with the contact pins, said movable contact means, when actuated, effecting electrical connections with said contact pins. A single actuator means is provided for each switching body means which is common to all the movable contact means thereof intended to be actuated, such single actuator means comprising a separate plug member means totally separatable from, but removably insertable into, said hollow internal cavity of said switching body means, said plug member means including actuating means for selective ones of said movable contact means. This separate, removably insertable plug member means, when inserted into said hollow internal cavity of said switching body means, serving to deflect selective ones of said contact means against the associated contact pins, whereby a given data distribution mode is effected. There is also provided programing template means having a respective cut-out for each plug member means substantially conforming to the cross-sectional shape of said actuating means on each of said plug members means, whereby said programing template means provides storage of a plurality of data distribution modes.
