Title: **Innovator Spotlight: Dennis D. Smith**

Introduction

Dennis D. Smith, an accomplished inventor based in Bartlett, Illinois, has made significant contributions to the field of thermal devices with his innovative designs. With a total of three patents to his name, Smith has demonstrated a profound understanding of thermal cut-off technologies, pushing the boundaries of what is possible in electrical safety mechanisms.

Latest Patents

Smith's latest innovations include a **thermal cut-off device with an activating spring** and a **temperature-sensitive spiral spring sliding contact device**. The thermal cut-off device operates with a first axial lead that extends through an insulating member and a second lead that makes contact within a conductive cylindrical housing. The electrical connection between the insulated lead and housing is maintained by a coiled helical spring, which, when exposed to a predetermined temperature, releases its stress due to a thermally fusible pellet, thereby breaking the electrical connection and preventing potential hazards.

The temperature-sensitive spiral spring sliding contact device features a casing with leads connected to a spiral spring forming an electrical contact. As the thermally-fusible pellet melts, the spring relaxes, allowing the conducting projection at its end to connect or disconnect from the matching curve on the fixed lead. This clever mechanism effectively helps manage circuit connections in response to temperature changes, enhancing safety.
