Electrical apparatus such as a switch

Abstract

Electrical apparatus comprises a first connection terminal (21A, 21B), a fixed contact (4A, 4B) connected electrically to said first connection terminal (21A, 21B), a second connection terminal, a movable contact (5), a conductive wiper (40) which carries said movable contact (5) and is connected electrically to said second connection terminal, a spring component for urging said wiper (40) towards either of two stable positions, specifically a conducting position in which said movable contact (5) is on the said fixed contact (4A, 4B) and an isolating position in which said movable contact (5) is not on the said fixed contact (4A, 4B), and a control member (60) connected mechanically to said conducting wiper (40); a fluid viscous substance (57B) being sandwiched between said fixed wall (12B) and said movable wall (69B) in each of said conducting and isolating positions as well as in each intermediate position between the latter.

Description

technical field

[0001] The present invention generally relates to electrical equipment of the type comprising: a first terminal; a fixed contact electrically connected to said first terminal; a second terminal; a movable contact; a conductive brush (balai conducteur) connected to said second terminal, a resilient element for urging said conductive brush to move to one or the other of two stable positions, each being a a conductive position in which the movable contact abuts against the fixed contact, and a disconnected position in which the movable contact is at a distance from the fixed contact; and mechanically coupled to the conductive The manipulation part of the brush. Background technique

[0002] Such electrical devices are already known, inter alia, from French patents FR 2,564,234 and FR 2,606,208.

[0003] When in operation, these electrical devices are almost inevitably a source of noise detrimental to the comfort of the environment.

[0004] In short, the nois...
