Patent No. (Basic): US 5283421 A 9402019406<br />
CPSC-IAG95-1145<br />
When a carriage <strong>of</strong> the toaster is in a lower positiou a switch (21) is closed and power passes through a bridge rectifier circuit (22)<br />
to au integratedcircuit ( 19), whick <strong>for</strong> the norsnaIcooking operatiom switches SCR (20) <strong>of</strong>f so that a relay (7) is energised, switching switches<br />
(8) and (9) onto energise heating elements (2) and (3). Power is also supplied to a latch (27) to hold the carriage in the lower position. If,<br />
however, a fault detection is input ffom a residual core balance (12) to the integrated circuit (19), SCR (20) is switched on so that power fkosn<br />
bridge rectit%r (22) is shorted. T%is causes relay (7) and latch (27) to be de-energised so thatthe heating elements (2) end (3) areturned <strong>of</strong>f and<br />
the carriage is returnedto the upper position, causing switch (21) to open. ADVANTAGE <strong>Pre</strong>vents unexpected energisation <strong>of</strong> appliance when<br />
power supply is re-cormected.<br />

PatentNo. (Basic): CA 2052781 A 9304059325<br />
A The method involves placing a secondary switch between the operating components <strong>of</strong> an .Ieckical appliance and a power source.<br />
The secondary switch has an open position and a closed position. In tie closed position electrical current flows fkom the power sonrce to the<br />
operating components <strong>of</strong> the electical appliance. Jnthe open position the flow <strong>of</strong> electrical current betweertthe power source and the operating<br />
components <strong>of</strong> the electrical appliance is dmrupted. The secondary switch has a fm sensing switch actuator in the <strong>for</strong>m <strong>of</strong> a heat sensor or a<br />
smoke sensor, such thatthe position <strong>of</strong> the secondary switch is alteredupon the presence <strong>of</strong> a f~e being sensed. USE E.g. <strong>for</strong> deactivahg electric<br />
stove if fwe originated tlom that appliance, <strong>for</strong> activating radio/akmn clock in pressnce <strong>of</strong> fwe as a warning to occupants <strong>of</strong> residence.<br />
