Power Switch
The Panasonic NB-G110P Toaster Oven has a common failure mode where the main on/off switch becomes increasingly intermittent.
1) If it’s not too bad yet try simply cleaning the switch: unplug the toaster oven, pry off the grey plastic on-off button to expose the head of the on/off switch and apply some electrical contact cleaner (CorrosionX or MG Chemicals Super Contact Cleaner or something similar) or, less ideally, 91% or better isopropyl alcohol. Work the switch a bit by turning it on and off a lot (still unplugged) and see if that doesn't fix the problem.
2) If the switch does need to be replaced (SW 15 on the circuit board) a fairly common 7x7mm 6-pin DPDT (dual-pole-dual-throw) switch will work as an acceptable substitute.
