<p>1. Enclosed electrical control panel, having a partition wall (4) separating a bus bar compartment or cable connection compartment (3) from a power switch compartment (2), which (4) comprises apertures (4a) for the penetration of contact arms of an actuator carriage (5) guidable in the power switch compartment from a dividing position into an operating position, which (4a) are covered in the dividing position of the actuator carriage (5) by a pair of cover plates (6) arranged parallel to the partition wall (4), which (6) abut each other in the covering position and can be moved apart by the movement of the actuator carriage (5) into the operating position, revealing the apertures (4a), by means of a lever mechanism extending between them and the actuator carriage (5), which lever mechanism comprises a lever (8) pivotable about a fixed axis (7) on the interior of a panel side wall (1), characterized in that the lever (8) comprises two limbs, of which ones is coupled to one of the cover plates (6) and the other engages with a roller (9) into a slot (10) of one plate (11) of a pair of plates (11, 11a) ; in that the lever mechanism is a scissor-type mechanism, consisting of the lever (8) and a second lever (12), and designed for the raising and lowering of the cover plates (6) in opposite directions ; in that the second lever (12) is coupled at one end to the free cover plate (6) and at the other end engages with a roller (13) into a recessed slot (14) inclined in the opposite direction to the slot (10) and arranged in the free plate (11a) of the pair of plates (11, 11a) ; in that the plates of the pair of plates (11, 11a) are connected to each other and are displaceably arranged in a fixed mounting plate (15), and in that there is coupled to the pair of plates (11, 11a) an intermediate lever (18), on to which a drive lever (20) engages which is deflectable by the actuator carriage (5).</p> |
