ABSTRACT:
A safety mechanism for disabling a portable room heater. A lever which extends from the heating face of the heater is coupled with a shut-off switch. Movement of the lever resulting from draping of an object over the heater opens the switch and shuts off the heater. A buzzer may be wired in parallel with the switch to provide an audible alarm when the switch opens.
