Abstract:
1. An overload protection switch comprising: a housing; a button pivotally connected to an upper portion of the housing and having a first extension and a second extension both extending from a bottom face of the button; a primary leg securely engaged with an inner side face of the housing and partially extending out of the housing, the primary leg having a first contact securely mounted on a top portion of the primary leg; a conductor securely attached to the primary leg; a second primary leg securely received in the housing and partially extending out of the housing; and a bi-metal plate securely connected to a top portion of the second primary leg and having a second contact securely mounted on a top portion of the bi-metal plate to selectively engage with the first contact and a deformation formed on a mediate portion of the bi-metal plate, whereby current passing through the switch will raise the temperature of the bi-metal plate as well as the temperature of the conductor so that the deformation of the bi-metal plate is forced to deform in advance to protect a sensitive electrical appliance connected to the switch.
