An overload protection switch has a conductor interconnecting the first primary leg and a second primary leg so that when current passes through the switch, the current not only raises the temperature of the bi-metal plate, but also raises the temperature of the conductor to enhance the deformation of the bi-metal plate such that the electrical appliance connected to the switch and having an ampere tolerance lower than that of the bi-metal plate is protected.
