Claims

[Claims for Utility Model Registration] 1. A temperature-responsive actuator 2 that acts on the lever 6 against the action of the first spring 9, and a second temperature-responsive actuator that acts on the lever 6 against the action of the first spring 9 on the lever 6. A latchable switch actuating member 1 in combination with a spring 20, wherein the action of the first spring on the lever and the action of the second spring on the lever form part of a manual latch mechanism 28.
6, the manual latching mechanism has two states; first, in the reset or unlatched state for normal cycling operation, the manual latching mechanism is activated by the opposing forces applied to the lever 6 by the two springs 9, 20; When a predetermined temperature is detected, the switch 15 is opened and closed, and in the latched state, the switch latches the member 16 and releases it from the lever 6, thus allowing the single A switching cycle occurs, which cycle is dominated only by the first spring 9;
A thermally responsive control device characterized in that when a temperature higher than the normal cycling operating range is detected, the cycling is terminated by automatic reset of the latch mechanism 28. 2. The thermally responsive control device according to claim 1, characterized in that the latching mechanism 28 is restrained in its latched state by the lever 6 until the end of a single high temperature switching cycle. 3 The switch operating member 16 is the switch 15 in the normally closed state.
The second switch is opened in normal cycling operation in response to the detection of a predetermined temperature dependent on the forces of the two springs 9, 20, and is opened by manual actuation of the latching mechanism 28. characterized in that the switch 15 is closed and then reopened in response to a temperature above said predetermined temperature only after resetting the latching mechanism 28;
2. Thermal responsive control device according to claim 1 or 2, for controlling a thermal appliance or an appliance incorporating at least one heating element. 4 The switch operating member 16 controls the switch 15, which is opened and closed in response to predetermined upper and lower temperature limits delimiting the normal operating range during normal cycling operation, and controls the latching mechanism 2.
8, the switch is opened by manual activation of the latching mechanism, and the switch is later closed again in response to the detection of a temperature higher than the upper temperature limit of the normal operating range only after resetting the latching mechanism. A thermally responsive control device according to claim 1 or 2 of the utility model registration claim. 5 characterized in that the latchable member 16 acts on the switch 15 via the displaceable plunger actuated by the lever 6 acting directly on the displaceable plunger 12 at the end of the single switching cycle. A thermally responsive control device according to any one of claims 1 to 3 of the utility model registration claims. 6 The plunger 12 is carried by and slidable relative to the lever 6 and has a head or flange 13 which the lever 6 engages at the end of said single switching cycle.
A thermally responsive control device according to claim 5, characterized in that it has the following. 7 Utility model registration claims 1 to 6, characterized in that the force applied by the second spring 20 to the lever 6 through the latched switch actuating member 16 can be adjusted by a setting cam that predetermines the temperature range of normal cycling operation. 2. The thermally responsive control device according to any one of paragraphs.
