FIELD: measurement technology. SUBSTANCE: cone checking device is intended to check angle of cone. With movement of measurement mechanism mobile contacts 20 move together with braces. When mechanism is balanced they can be either closed or open with immobile contacts. Depending on closing or non-closing of pairs of mobile and immobile contacts proper lamps of light annunciator go on signalling whether checked part is good or rejected. EFFECT: simplified design, increased operational reliability. 1 dwg
