Abstract
A safety power cutoff arrangement is disclosed for appliances which utilize membrane panel switches on their control panels causing electrical power to the appliance to be shut off in the event of damage to the control panel. The safety cutoff arrangement comprises a conductive track pattern formed over the outermost circuit sheet forming the membrane switch and interrupter circuitry which requires the continuity of the conductive track pattern to be maintained for electrical power to be continued to be supplied to the appliance circuitry. In the event of damage to the control panel, breaking of any segment of the conductive track pattern results in the interrupt safety circuit cutting off power to the appliance.
