My electric kettle recently broke. When I got into the guts of it, I noticed there were a lot of weird components that weren't really used, or didn't seem that useful. When I searched youtube for help, I found out those components were for kettles with a physical on/off switch. Mine didn't have the switch, but everything else on the inside was still there.
