Patent ID: 7600468

Claim:
A toaster, comprising: a toasting housing; a toasting compartment received within said toasting housing for heating at least a bread; a PCB circuit provided in said toasting housing for managing a toasting process; and a relay switch arrangement, comprising: a switch casing having a top stand; an electromagnet assembly supported within said switch casing, comprising an electromagnet, and an engaging metal having a fixing end supported onto said switch casing and a free end detachably engaged with said electromagnet at a position above said electromagnet; an actuating member, having a securing end hinged onto said top stand, and an engaging end rotatably coupled to said free end of said engaging metal, wherein said actuating member is shifted between a power-on position and a power-off default position; a homing spring biasing against said actuating member for maintaining said actuating member in said power-off default position; a power on/off arrangement, having a power slab securely mounted onto said switch casing and electrically connected to a power source, a switch leaf electrically connected to said electromagnet and moveably supported within said switch casing, and a pair of contacts respectively provided onto said switch leaf and said power slab at corresponding mated position; wherein in said power-on toasting position, said actuating member and said switch leaf are driven to approach towards said power slab until said pair of contacts engaged to complete said PCB circuit to toast said bread and meanwhile to charge said electromagnet attracting said engaging metal in position, such that said attracted engaging metal will tightly lock said switch leaf being engaged with said power slab during said toasting process; and wherein in said power-off default position, said PCB circuit is powered off enabling said electromagnet to release said engaging metal, said homing spring will upwardly push said actuating member thus driving said engaging metal tilt up so as to disengage said pair of contacts respectively provided onto the engaging leaf and power slab in practice for security purposes.
