The circuit between the light source and the current source has two parallel coupled switches (9). The moving substance (1) has a magnet (8) which in the extreme positions of the moving substance comes to proximity of one of the switches (9), in which case the switch (9) closes and the light source (11) lights. The moving substance (1) has been supported on two crosswise link arms (3) in a way that the lower ends of the link arms (3) have been fastened with bearings to the case (2) and the upper ends have been fastened with bearings to the moving substance (1). |
