In using such circuitry, operators will inadvertently apply the circuitry to voltage areas in excess of the prescribed voltage limits and this will of course damage the circuitry thereby rendering the testing device incapable of further use and requiring its replacement.
  • Another way to protect electrical circuitry is to use a bimetallic member which will open the circuit when the current exceeds a certain value. Use of bimetallic members is expensive.
  • the present invention overcomes these drawbacks by providing a thermal switch in circuitry which will open the circuit when a predetermined temperature is reached which is determined by the current flowing therein and it can be closed again thereby enabling the circuitry to be reused.
  • An object of the present invention is to provide a thermal switch in an electronic or electrical circuit which will open when the current exceeds a predetermined level.
  • Another object of the present invention is a thermal switch for an electrical or electronic circuit which can be closed again without replacing any parts.
  • a further object of the present invention is the provision of a thermal switch which precisely operates at a predetermined temperature.
  • An additional object of the present invention is to provide a thermal switch that is inexpensive for use in connection with electrical or electronic circuitry.
  • a still further object of the present invention is a thermal switch having the central portion of resistor means disposed in close proximity to the low melting point solder which maintains the movable contact means in electrical engagement with the stationary contact means.
  • FIG. I is a top plan view of a part of a substrate on which a thermal switch is located;
  • FIG. 2 is a side elevational view of FIG. 1 with the movable contact member in the open position;
  • FIG. 3 is a top plan view of an alternative embodiment of the invention.
  • FIG. 4 is a top plan view of a further embodiment of the invention.
  • FIG. 5 is a view taken along lines 5 5 of FIG. 4.
  • a substrate I which is generally made of aluminum oxide or some suitable dielectric material.
  • Conductive members 2, 3 and 4 are carried by substrate 11.
  • Conductive members 2 and 4 are connected to other components and other conductive members would be located on substrate 1 and these are not shown in the interest of brevity as well as not being essential to the invention.
  • Ends of conductive members 2 and 3 are spaced from each other and they are bridged by a switch member 5 having one end secured to either end of conductive members 2 or 3 via welding or in any other conventional manner.
  • switch member 5 is shown in its open position and it is made from a suitable material having spring characteristics which is initially formed having an arcuate configuration.
  • the material from which switch member 5 can be made is generally beryllium copper, phosphor bronze, silicon bronze, steel, or any other conductive material having the desirable spring characteristics.
  • Low temperature solder 6 having a predetermined melting point is placed at the end of either conductive member 2 or 3 and the free end of switch member 5 is soldered in position thereby connecting conductive members 2 and 3.
  • Solder t3 is a conventional solder and it is selected in accordance with the melting point at which the switch means will open.
  • the switch means is defined as stationary contact means comprising one of the ends of conductive members 2 or 3, the free end of switch member 5 and the solder 6 of a predetermined melting point.
  • a resistor 7 is connected between a section 8 of conductive member 3 and an end of conductive member 4 and its center is disposed in close proximity to the soldered end of the switch means and the reason for this is that the hotest point of the resistor 7 is at or about its center and this will direct the heat right at the soldered end. It is desired that substrate l have proper thermal conductivity to conduct the heat being generated by resistor 7 toward solder 6.
  • the switch means is closed by soldering the free end of switch member 5 to the end of conducrent passing therethrough and resistor 7 remains at or below a predetermined level, solder 6 will not melt and normal circuit operation will continue.
  • the heat being generated by resistor 7 causes the solder 6 to melt and the switch means opens due to its spring characteristics thereby preventing any damage to the circuitry on substrate )1.
  • the solder 6 is reheated and the free end of switch member 5 is resoldered onto the end of conductive member 2 or 3 and the circuitry can be reused without having to be replaced.
  • the switch means and the resistor in series therewith constitute a reuseable thermal switch means to prevent excessive voltages from permanently damaging electrical circuitry means.
  • FIG. 3 illustrates an alternative embodiment of the thermal switch wherein resistor 7a is disposed under switch member 5a and a thin piece of electrically insulating material 9 is secured over the central portion of resistor 7a in order to prevent any shorting between switch member 5a and resistor 71;. As can be discerned, the center of resistor 7a is positioned in close proximity to the soldered end of switch member 5a.
  • FIGS. 4 and 5 illustrate another embodiment of the invention wherein conductive member 3b extends through opening in substrate 1b and has a section 8b extending along the bottom surface of substrate 1b in alignment with conductive member 3b.
  • Resistor 7b connects conductive member 4b with section 8b, and it is disposed in alignment with switch section Sb which connects conductive members 2b and 3b so that the central portion of resistor 7b is disposed in close proximity to the soldered end.
  • a thermal switch comprising:
  • a hybrid solid state means including a substrate of dielectric materialhaving first, second and third conductive means secured on surface means thereof; a switch member of resilient material having a first end secured to said first conductive means and a second end disposed along said second conductive means;
  • resistive means having one end connected to said third conductive means and another end connected to said first or second conductive means and being disposed adjacent said switch member, said electrically conductive heat softenable material being softened upon heat generated by said resistive means reaching a predetermined limit thereby causing said second end of said switch member to move free of said second conductive means.
  • a thermal switch according to claim 1 wherein said switch member comprises an arcuate shape in its normally open position.
  • a thermal switch according to claim 1 wherein said resistive means is disposed on another surface means opposite to said surface means on which said switch member is located and a central portion of said resistive means is disposed in alignment with said heatsoftenable material.
