<p>Single modular system for manufacturing a small electrical device, characterised in that it comprises: a mechanism-carrying module which is a hollow base intended to receive and to house the mechanism and of which the particular feature is to be single and common to any of the mechanisms and which has a regular configuration to standardised dimensions corresponding to submultiples of the same module defining the system: <IMAGE> a double termination system having the double function of termination by gripping 4 and another with the aid of bolts and screws 5 and 5a, two-position and multipurpose contacts composed of: circuit-breakers/switches 2, 6, 12 and contacts for sockets, a covering socket plate, an internal power-supply distributor 13, a multipurpose luminous indicator 11 which can be incorporated and oriented if required, a member for protection against fortuitous or inappropriate engagement, access or use, a circuit-breaker/switch with a rocker lever having a short stroke and minimal surface unevenness of the taper key, a key-operated circuit-breaker incorporating a special cover and means for the unitary or back-to-back mounting or assembly for all the ranges of taper keys. <IMAGE></p> |
