<p>An improved proximity switch (30) has been described. The proximity switch (30) includes control electronics (34) and a sensor (32) . The sensor (32) is remotely mounted from the control electronics (34) and is coupled to it via a wire (33) connection. The switch (30) is more economical to manufacture due to its novel arrangement. The control electronics (34) and the sensor (32) may each be provided with a heating element (36). The heating elements keep the electronics (34) and the sensor (32) warm and prevent moisture from condensing on the electronics (34) and the sensor (32). <IMAGE></p> |
