Analogue indicating organ in crystalline material

摘要

The unit (10) has a main body (11) made of silicon based crystalline material i.e. monocrystalline silicon, and with a proximal portion in which an axle hole is formed that is adjusted on a drive axle. The body includes a distal portion that forms an indicator section of the unit and is connected to the proximal portion by a beam. A width of the beam in a transverse plane to the drive axle is comprised between two hundred to three hundred microns. The body is provided with a coating i.e. metal, made in a material different from the body.
