<p>A thermomagnetic switch (1) is described comprising: a box-type body comprising an intermediate wall (3) which defines respective phase and neutral housings (3f, 3n), movable phase and neutral contacts (18f, 18n) destined to come into contact with respective fixed phase and neutral contacts (6f, 6n), a kinematic mechanism connected to the mobile contacts (18n, 18f) to bring them from a closed position to an open position, a push button (11) that can be operated from the outside and that is connected to the kinematic mechanism, and a coupling lever (26) - connected to the kinematic mechanism - which can be operated through the intervention of a thermal (22) and/or of an electromagnetic (50f) and/or of a differential device (100, 50d). The kinematic mechanism comprises a contact-carrying lever (117) made in a single piece and provided with two arms (121), which extend into the phase and neutral housing (3f, 3n). Each arm (121) comprises a seat (118) able to receive the respective movable phase and neutral contact (18f, 18n).</p> |
