FIELD: mechanics.;SUBSTANCE: proposed indicator comprises micro switch fitted in switching mechanism initiating contactors and furnished with lever. The latter is arranged inside aforesaid mechanism to take up driving force and to generate electric signal indicating air switch closed state. It comprises terminal to transmit electric signal to distant point, and cut-in link to depress micro switch lever to make it generate and output electric signal only when closing spring accumulates elastic strain energy.;EFFECT: on-line data on air switch state for distant user.;11 cl, 10 dwg
