Claim of US Patent No. 9,478,381

1. A modular electrical switching device comprising:
a switching block comprising unitary switching blocks respectively comprising electrical switching means;
an actuation block comprising an actuation module of the unitary switching blocks, the module incorporating an electromagnetic
actuator controlled by control means;

means allowing the actuation block to be removably fixed onto the switching block;
a removable electrical control module incorporating the control means and comprising adaptive connection means configured
to be interconnected with an actuation coil of the electromagnetic actuator when the removable electrical control module is
positioned on the actuation module;

rapid fixing means allowing a removable fixing of the actuation block onto the switching block and comprising at least one
coupling hook configured:

to fix and secure the switching block to the actuation block, and
to collaborate with an actuation device of a mobile contact of the unitary switching block to transmit movement of the electromagnetic
actuator to the mobile contact;

the coupling hook being secured to a mobile keeper of the electromagnetic actuator.
