Electric heater circuit

An electric heater circuit for an electric heater comprising:

• a. heater coil means for generating heat,
• b. a temperature sensitive switch for deactivating the heater means when the temperature inside the electric heater exceeds a predetermined threshold temperature, the temperature sensitive switch being normally closed,
• c. a tilt sensitive switch for deactivating the heater means in response to tilting movement of the electric heater beyond a predetermined amount relative to a normal upright position, the tilt sensitive switch being normally closed, and
• d. signal means coupled in parallel with said temperature sensitive switch and said tilt sensitive switch for providing a signal directly in response to either the temperature sensitive switch being opened as a result of the temperature inside the electric heater exceeding the predetermined threshold temperature or the tilt sensitive switch being opened as a result of tilting movement of the heater beyond the predetermined amount relative to the normal upright position.

An electric heater circuit for an electric heater comprising:

• a. input means for connecting the electric heater circuit to a source of power,
• b. a temperature sensitive switch coupled between the input means and the heater means responsive to temperature inside the electric heater, the temperature sensitive switch being normally closed, the amount of current passing through the heater means depending in whether the switch is open or closed,
• c. a tilt sensitive switch coupled between the input means and the heater means responsive to tilting movement of the electric heater, the tilt sensitive switch being normally closed, the amount of current passing through the heater means depending on whether the switch is open or closed, and
• d. a signal means for providing a signal directly in response to either the temperature sensitive switch being opened or the tilt sensitive switch being opened.
