<p>This invention relates to a switch and more particularly to a temperature responsive switch used in a catalytic converter generally found in internal combustion engine exhaust systems. The temperature switch is an independent self-contained unit that is mounted directly on the converter and has a sensing element that extends into the converter to activate switch contacts to provide an initial warning as well as a second warning that the catalyst within the converter may become ineffective due to deterioration of the catalyst, and therefore maintenance of the converter is required.</p> |
