Definitions
- the noise starts when the moving contact abuts against the fixed contact, which happens in practice abruptly. This results in a more or less loud noise that spreads quickly to the rest of the device.
- the viscous fluid substance moderates the speed of approach of the moving contact and therefore allows an attenuation of the impact between the movable contact and the fixed contact, which prevents any untimely rebound of the contact O
- This attenuation of the shock also causes a strong attenuation of the noise generated and more generally a smooth operation, while flexibility, particularly comfortable.
- the damping viscous fluid substance has the advantage of not influencing the pressure exerted between the fixed contact and the movable contact in the conduction position. Indeed, in this abutment position, the moving contact is immobile (zero speed) and no fluid friction force disturbs the action of the elastic element.
- said electrical apparatus comprises a tank containing said viscous fluid substance, and a blade immersed in said tank, said tank and said blade having said fixed wall for one and said movable wall for the other;
- said blade comprises said movable wall and said tray comprises said fixed wall; said blade is rigidly connected to a lateral element of said operating member;
- Said operating member is a button formed in one piece with two said blades located on either side of said key, each of said pay being immersed in a respective tray containing said viscous fluid substance.
