Current thermometer is a patch board designed to solve the overload of electronic. Originated from the inspiration of thermometer, it informs the user of the magnitude of current by telling the user of the safe condition through the mercury column like signal light.
Once plugged in, it would show the user of the current magnitude with a glowing thermometer. Resembling the thermometer, the peak load would be the maximal magnitude the patch board could afford, once overloaded the plug would cut off the rest plugs, and give off caution signals by the glowing thermometer.
