Abstract

Abstract PURPOSE: To make it possible to prevent the operation of heat source, by providing a resistor for setting voltage so that is can be attached and detached freely to and from the voltage comparator, and forming the unit by means of simple structure which provides one connector even in case when this resistor is not connected. CONSTITUTION: Resistors 5W7 for setting voltage are arranged on the subsubstrate 10, and are provided so that they can be attached and detached freely to and from the voltage comparator 3. A resistor 4 is provided to said subsubstrate 10 having connectors 11aW11e. In case of said structure, in case when the subsubstrate 10 has not been connected, as for the voltage of the input terminal, the + side becomes larger then the - side, and therefore an output of the voltage comparator 3 becomes an H level, and no combustion operation is caused.
