On a simple 220 V home appliance equipped with a manual timer switch ( a knob that you can turn clockwise up to the desired position -time- and will then automatically turn counterclockwise for the chosen time period ), I would like to either bridge the switch with an additional on/off switch, or replace the timer by an on/off switch.
The goal is to bypass the 1 hour limitation imposed by the manual timer itself by adding an "always-on / always-off" capability.
Q Can I do it "just like that" and if not, how could I easily do it at home with basic electronic tools ?
What if I intend to replace the manual timer by a digital timer ? I guess it might itself have to be powered somehow.
Thank you for your help.
