Abstract
A safety disconnect device for use in detecting a gas in a confined space, such as a flashlight, comprising the use of a catalytic gas recombination material, such as palladium, in conjunction with a heat-sensitive conductive element connected as a switch, in a circuit containing a power supply so that the heat generated by the reaction of the detected gas with a reactant on the surface of the catalytic material will alter the heat-sensitive conductive element to open the circuit.
