A system of coding plates having two circuit switch supports, whereby two grooves in each of the two supports of the circuit switch designate four capacity parameters such as voltage, direct current, interrupting capacity and instantaneous current. Two cell plates are mounted on a control panel containing the sliding circuit switch. The cell plates each have two tongues, whereby the tongues designate the same parameters as the four parameters used by the circuit switch. The width, height or depth of the grooves and tongues designate the particular value for each capacity. |
