555 triggered by a switch and thyrister problem!! PLEASE HELP!!

Hi,

I have a problem because a switch is working as a reset switch for the solenoid as well as a tension release mechanism for the pulley. The thyristor is also triggering the 555 chip (monostable). Do you guys have a solution, please do not tell me to have 2 switches for the tension release as well as the reset for the solenoid circuit.

PLEASE SEE MY ATTACHED PICTURE AND MY VIDEO ON YOUTUBE EXPLAINING MY PROBLEM FURTHER!!

Give us all a clue. What's the circuit SUPPOSED to do. That thyristor can never turn off once you fire it you realise ?
