foam saver

After completely ruining a $40.00 plank of nice 3/4 in core cell foam by leaving it in my oven too long. I decided to make a timer that shuts off my oven automaticly. I'm toasting my foam with ten 250W heat lamp bulbs so I needed a heavy duty switch..... The cooking timer triggers the coil that pulls an internal steel tube that pulls a rod that throws the switch that kills the power to the outlet that my oven is plugged into. The wire rail to the left de-energizes the coil once the main switch is thrown........the cooking timer set me back $1.97 and I scrounged the other stuff and spent twenty minutes building this very crude but functional relay.
