<p>The technical problem solved by the present invention is a constructional solution to locking a detachable module, which allows securing the module from falling out from the base part of a surge protective device. The essence of the lock of the detachable module in the base part of the surge protective device of the invention lies in that locking buttons of a symmetrical assembly run along a specially shaped recess while the module is positioned and said buttons engage in the end position into a semi-circular horizontal section. When the buttons are simultaneously moved, the external side of the module indicates the mode »locked« or »unlocked«.</p> |
