Mercury Thermostats
A control device typically used in a heating and/or cooling system to maintain a set temperature. Older models contain liquid mercury and are considered hazardous waste. Newer models are electronic and considered electronic waste when non-working.
In the old style of thermostats with a lever or switch - not the newer electronic kind - there is mercury inside the sealed glass tilt switch.
Properly recycling mercury thermostats is the law. Use the Thermostat Recycling Location Finder to find free drop-off sites near you. Residents, contractors, and businesses all qualify for rebates of up to $30 per mercury thermostat.
