switches

[merlin]

hi there i would like to know if its possible to ha key have 4 key switches and a number key bap to work together

basically you have to turn all 4 within 3 seconds or so witch can then power the key pad where i can enter a 6 digit pin witch can then power a relay until the key switches are turned off


but if all the switches were NOT turned on at the same time or within 3 seconds or so system will need a restart to work again and would be nice to have like an emergency witch when pushed it re-locks the system in a seance (basically when the button is pushed it will unpower the relay and require a restart to try and work again) i would also like a failsafe feature were the system will not start unless all

switches are off if you need any more info pleas ask
