Abstract
A probe thermostat is disclosed having a positive-off element included in the switch portion of the thermostat which prevents the switch from being closed when the variable control means of the thermostat is set to its extreme or 'off' position. The positive-off element assures that the switch will be open even if a mulfunction occurs in the thermostat which would otherwise result in closing of the switch and undesirable current flow to the heating element. The illustrated form of positive-off element comprises an insulative threaded fastener attached to a portion of the base of the thermostat which engages one of the contact arms to hold it away from the other contact arm when the variable control means is set to its extreme 'off' position.
