1. An electronic switch comprising:
- a first terminal adapted to receive an input voltage;
a second terminal;
an environmental condition sensor configured to receive an input and providing an output; and
a switching element receiving the output of the environmental condition sensor, the switching element adapted to operate in a first state when a voltage on the first terminal is greater than a high threshold voltage, and the switching element adapted to operate in a second state when a voltage on the first terminal is within a low threshold range; and
wherein the input voltage provides power for the electronic switch, andwherein the first and second terminals are the sole electronic connections of the electronic switch.

Abstract
A system adapted to replace a mechanical switch with an electronic switch, without the need of additional wiring. The electronic switch includes a bridge array for sensing a characteristic, e.g., temperature or pressure, and an electronic circuit having a switch. As the characteristic of the bridge array varies a switch changes states.
