Here is overview of what is involved. I have a intermatic astrological timeclock controlling lighting contactor . I want to add single pole switch to be able to turn contactor on for lights at any time and have timeclock turn off. Basically time clock will have contactor on at 5pm, off at 8am, during certain events lights will be turned on . Right now the lights are being turned by overriding timeclock. Want to use single pole to keep unwanted people from timecclock,seems setting are often changed by mistake
