I have an existing porch light on a (spring-style) timer. I would like to add a switch for more convenience, so that the light could be manually turned on for a few seconds or for several hours.
The function of the 3 way switch would be to turn the light on directly or transfer power to the timer (in series). Would this be an okay (code compliant) way to add a (simple) switch to a timer?
Another part of the reason I ask, is because a digital timer (with simple on/off button) is like $30 in my area, whereas a 3 way switch is like $1.50. And the timer just happens to be in a box with an outlet switch that could easily be eliminated (meaning, I don't have to buy a remodel box or anything else).
Edit- New picture for clarity:
