Door switch on large oven went out.

First, I called my son over to do the repairs. He shut the power to the oven off at the breaker box, he then unplugged the oven from the wall outlet, just to be extra safe. Next, he gently pried the door switch out from the face of the oven using a small flat bladed screw driver. Once the switch was out he tied a piece of twine to the connector/plug before unplugging the switch. He then plugged the new switch in, untied the twine and carefully pushed the switch back into the hole on the face of the oven. Reconnected the pigtail to the outlet and turn the power back on at the breaker box. After watching my son do this repair I believe I could have done it and I'm 70 years old, well everything but move the oven out to unplug it from the wall outlet.
