Abstract: A thermostat includes a heat-conductive guide with an upper side and a lower side; a top board with an upper side and a lower side; a double-metal plate; a first rivet; a short spring plate with a first electrical contact disposed thereon; a long spring plate being connected with the short spring plate; a contact board with a second electrical contact disposed thereon; and a second rivet. The upper side of the heat-conductive guide is connected with the lower side of the top board through the first rivet. The lower side of the heat-conductive guide is connected with the double-metal plate through the first rivet. The long spring plate and the contact board are connected with the lower side of the top board through the second rivet. The double-metal plate is configured to sense a temperature of the heat-conductive guide and actuate the short spring plate accordingly.
