SAFETY SWITCH ACTUATION DEVICE Russian patent published in 2025 - IPC H01H3/02 H01H17/12 

FIELD: mechanical engineering.

SUBSTANCE: invention relates to safety switch actuation device (1) for holding push-button switch (2) switched on and off remotely, in particular in elevators. At that, actuation device (1) comprises plunger (3) with possibility of returning by means of external inspection from ready position, in which it does not switch pushbutton switch (2) into active position, in which it holds said pushbutton switch (2) on, actuation device (1) has remotely controlled linear drive (4), return spring (11) and return drive (12) and is made so that plunger (3) is made with possibility of connection to return drive (12) by remotely controlled linear drive (4), which is preferably actuated by Bowden cable (6) under tension of return spring (11), which, after disconnection of linear drive (4), is compressed by return spring (11) to a position farther from push-button switch (2), thereby gripping plunger (3) into readiness position.

EFFECT: possibility of finding out the cause of emergency braking before the elevator can be put back into operation.
