ABSTRACT:
An automatic control for egg cookers, baby bottle warmer, etc. is designed around a conventional slide switch of the type normally biased to the open position. Manually actuated means are provided to move the slide switch to its ON position, whereupon a mechanical latch automatically latches onto the knob of the slide switch to hold it in its ON position. When the cooking has been completed, a bi-metal releases the latch and permits the biasing means to open the switch and terminate the heating.
