<p>In an apparatus operating, as desired, with gas or electricity (optionally with low and high voltage) and fitted with a control valve (1) with ignition pusher (7) comprising a rest position (shown for its control button (8) fixed angularly), as well as with a switch (2) associated with heating electric circuits, there is provided between (1) and (2) a safety mechanism preventing the simultaneous operation of the apparatus with gas and electricity. This mechanism comprises a drum (17) keyed on the shaft (14) of (2) and a finger (16) which, as soon as (8) it is pushed back from its closing position of (1), engages a groove (17a) of (17) thereby blocking (2) at the opening whereas if (2) is in a closed position, (8) is blocked at the closing of (1).</p> |
