Robot MPM Kasia Stopped Working: SENUR 116-5 Switch, Mechanical Transfer & Electronic Board Issue

The robot suddenly stopped working. I undressed it, cleaned the contacts on the electronic board, the engine starts but only after turning the switch lever in the upper right corner of the photo with a view of the electronics board. But how is the mechanical movement transferred from the handwheel to this switch? Nothing fell out when I undressed
This weird switch is SENUR 116-5, Google doesn't find it
I also found an assembly drawing of the robot on the net (the switch has the designation D / 4308 and D / 6523 on it)

You probably have a "collar" or a plastic tab on the vessel that appears to go into the slot of the robot when the vessel is in place and then pushes the lever and allows the motor to start. At least from the photos on the net, I conclude so

Not when dismantling now, but maybe the plastic on the dish is broken (maybe when washing or taking it off).

Thanks. I also thought so, I will ask the robot's owner about this vessel
