Abstract

A resetting element for transmitting resetting force to a thermal switch. The resetting element includes a first end and an elastic element configured to transmit a force received at the first end to the reset switch of the thermal switch, wherein the elastic element is prevents damage to the thermal switch by decreasing the force transmitted to the reset switch from the first end.

First claim

The invention claimed is:

1. A resetting element for transmitting a resetting force to a reset switch of a thermal switch, comprising:
an elongated body having a first end configured to receive the resetting force and a second end configured to abut a housing of the thermal switch; and
an elastic element fixedly attached to the elongated body and configured to transmit at least a portion of the resetting force received at the first end to the reset switch of the thermal switch, wherein the elastic element is configured to decrease the resetting force transmitted to the reset switch from the first end.

2. The resetting element of claim 1 , wherein the elastic element is movably positionable to contact the reset switch, and wherein the second end of the resetting element is configured to move between a first position spaced apart from the housing of the thermal switch and a second position in contact with the housing of the thermal switch, wherein the second end of the resetting element in the second position limits movement of the elastic element toward the reset switch.

3. The resetting element of claim 1 , wherein the elongated body extends from the first end to the second end along a first axis, and wherein a first portion of the elastic element is connected to the elongated body and extends along a second axis that is substantially perpendicular to the first axis.

4. The resetting element of claim 3 , wherein the elastic element further comprises an abutment portion configured to contact or selectively contact the reset switch, wherein the abutment portion extends along a third axis that is substantially parallel to the second axis.

5. The resetting element of claim 4 , wherein the elastic element further comprises an s-shaped portion connecting the first portion to the abutment portion.

6. The resetting element of claim 1 , wherein the elongated body is stiffer than the elastic element, and wherein the elastic element is connected to the elongated body at a portion of the elongated body that is closer to the second end of the elongated body than to the first end of the elongated body.

7. The resetting element of claim 1 , wherein the elongated body is configured to move along a first axis in a first direction in response to the resetting force being applied in the first direction, wherein the elastic element is configured to transfer the resetting force to the reset switch along a switch axis in the first direction, wherein the switch axis is spaced apart from the first axis.

8. The resetting element of claim 2 , wherein the elastic element is configured to move and transfer a spring force to the reset switch when movement of the second end of the elongated body is limited by contacting the housing of the thermal switch.

9. A heat responsive device, comprising:
a thermal detection device, comprising:
a thermal sensor configured to cause discontinuity between a first terminal of the thermal sensor and a second terminal of the thermal sensor upon exposure of the thermal sensor to a temperature greater than a preset threshold temperature; and
a reset button configured to receive a force to reset the thermal sensor; and

a resetting element, comprising:
a first end configured to receive a resetting force; and
an elastic element configured to at least partially absorb the resetting force and to transmit the force to the reset button of the thermal detection device to reset the thermal sensor, wherein the force is less than or equal to the resetting force.

10. The heat responsive device of claim 9 , wherein the resetting element further comprises an elongated body extending from the first end to a second end, and wherein the elastic element is fixedly attached to the elongated body.

11. The heat responsive device of claim 9 , wherein the first end is configured to receive the resetting force applied to the first end in a first direction, and wherein the elastic element is configured transmit the force to the reset button in the first direction.
