Реферат: The oscillator control button includes an automatic control circuit for the frequency CAF (9-10) and a control circuit (G). The control circuit (G) is connected to the CAF control circuit (9-10) and to regulating elements (5-6). These elements (5-6) control coarse and fine pistons (4 and 3) of the high stability oscillator (1). The control unit (5-6) via several recopy elements. The unit (G) is also connected to exterior units controlling acuation (11) of the button and or frequency change (12).
