Abstract: A sealing system can be mounted between a body of a vehicle and a box fastened to the body. The body and the box include a first opening and a second opening, respectively, opposite each other. The sealing system surrounds the passage and includes a bellows having a first end in contact with the body so as to surround the first opening, and a second end in contact with the box so as to surround the second opening. The sealing system comprises a compression spring. Each end of the spring acts on one of the two ends of the bellows so that the spring moves the two ends of the bellows away from each other.

Abstract: This electric switching device (2) comprises a first module (4), including a first support (42) on which a circuit breaker (44) is mounted, and at least one second module (6), including a second support (62) on which an electric component (64) is mounted that is able to be associated with the circuit breaker. In particular in order to facilitate the maintenance of this switching device, the latter includes guiding means (81 and 82) that are able to guide the first and second supports relative to one another between a disassembled configuration, in which at least one of the first and second modules is disengageable from the guiding means independently of the other, and an assembled configuration, in which the circuit breaker and the electric component are in a relative connection position and are able to be electrically connected to or disconnected from one another.
