The electrical switch comprises a micro-switch (5), an actuating lever of the micro-switch, and a gasket to seal between the micro-switch and the lever. The actuating lever is moved between two positions including a rest position and a switching position in which it operates the micro-switch. The gasket has an elastic peripheral end cooperating with a complementary extension of the lever in the resting and switching positions of the lever. The elastic peripheral end has a tubular shape, and forms a bulge protruding at the opening of the tube. The electrical switch comprises a micro-switch (5), an actuating lever of the micro-switch, and a gasket to seal between the micro-switch and the lever. The actuating lever is moved between two positions including a rest position and a switching position in which it operates the micro-switch. The gasket has an elastic peripheral end cooperating with a complementary extension of the lever in the resting and switching positions of the lever. The elastic peripheral end has a tubular shape, and forms a bulge protruding at the opening of the tube towards the complementary extension. The extension has a complementary cylindrical form inserted in an opening of the tube, and comprises a unit for guiding and holding the peripheral end. The opening of the tube has a diameter less than the diameter of complementary extension. The unit for guiding and holding comprises an annular groove receiving the peripheral end. The gasket is partially overmolded, and comprises a thermoplastic elastomer, a cover for the micro-switch and a side chimney to connect the cover to the elastic peripheral end. |
