Abstract
A toaster includes an activation element, a power circuit, a heating device and a control device. When the activation element is moved to turn on the power circuit, the control device is powered such that an electromagnet is activated to attract a retaining element to hold the activation element and to actuate a two-state switch, which allows passage of electrical power to the heating device. After a time interval has elapsed, the control device stops the electromagnet from attracting the retaining element such that the retaining element no longer actuates the two-state switch, which cuts off electric power provided to the heating device.
