Evening all, I have inherited a job where the 24 hour doors are shunted via a standard single gang/single pole key switch (ks1) there’s numerous faults on the doors but been scratching my head wondering how to go about cabling this whilst incorporating the resistors for the double doors and or a shunt resistor at the switch. Only way I can imagine doing it is by carrying additional cores through from the panel to the contacts
