Abstract
A fuseless breaking switch comprising essentially a casing, an alloy plate, a first and a second prong, and a spring blade. The switching on of the button allows a closed circuit through the alloy plate and the prongs. An overload of current will cause the alloy plate to flex and thus break the circuit.
Claims2
A fuseless breaking switch comprising a casing, a button and a pair of prongs, characterized in that the button is mounted at the center of the casing, the bottom of the button is movably seated on a branched rod which is secured to the casing, a second rod is movably attached so as to communicate between the button and an alloy plate which is substantially perpendicular to the second rod, a first end of said alloy plate being attached to a spring blade and a second end of the alloy plate is affixed to the casing, wherein the alloy plate is situated such that the first end of the alloy plate abuts an end of the second rod, and a second end of the spring blade is affixed to the casing;
- and wherein the pair of prongs are in electrically conductive communication with the alloy plate when the switch is in a closed position, the conductive communication being facilitated by a protrusion on one of the prongs which contacts a protrusion near the first end of the alloy plate.
