<p>An electrical connector for a telephone system comprises a housing moulded in one piece from insulating material with a plug receiving cavity opening at a plug receiving mouth at a front mating face of the housing, a row of spring contacts anchored in a housing cavity wall to extend into the cavity so that the contacts will be resiliently engaged by respective contacts of a complementary plug when inserted through the mouth into the cavity. A compartment with a contact set extends alongside and opens into the plug receiving cavity. A cam integrally formed with a wall of the cavity extends into the plug receiving cavity into the insertion path of a plug, which will, on insertion, urge the cam through the opening and into the compartment, moving the contacts of the contact set relatively apart and breaking the circuit.</p> |
