The switch consists of a supple and deformable element (1) with a push-button tip (7) and a conductor (2) which makes contact with a commutation zone (6) on a circuit panel (3), and is equipped with seals (8, 9, 10) to isolate the commutation zone from the outside atmosphere. One seal is in the form of a ring (10) with claws (11) which clip into holes (12) in the circuit panel and a groove (9) round the inner surface of the ring to receive an edge seal (8) on the supple element (1). The conductor consists of a flexible dome fitted between the supple element and the commutation zone of the panel.
