| 20090040008 | THERMAL ACTUATOR FOR A MEMS-BASED RELAY SWITCH - A representative embodiment of the invention provides a thermal actuator for a MEMS-based relay switch. The thermal actuator has an “active” arm that is movably mounted on a substrate. The “active” arm has (i) a thermal expansion layer and (ii) a resistive heater that is electrically isolated from the thermal expansion layer. The thermal expansion layer is adapted to expand in response to a temperature change induced by a control current flowing through the resistive heater, thereby bending the “active” arm and moving that arm with respect to the substrate. Due to the fact that mechanical and electrical characteristics of the “active” arm are primarily controlled by the thermal expansion layer and the resistive heater, respectively, those characteristics can be optimized independently to obtain better operating characteristics for MEMS-based relay switches of the invention compared to those attained in the prior art. | 02-12-2009 |

Thus, the overheating of the internal device can be detected without delay, and the safety of the apparatus including the internal device can be increased. | 10-29-2015 |

| 20160027598 | TEMPERATURE-DEPENDENT SWITCH WITH INSULATING FILM - A temperature-dependent switch having a housing that comprises a cover part with an upper side as well as a lower part with an inner circumferential shoulder and a circumferential wall above the shoulder, which wall comprises an inner side above the shoulder, has a temperature-dependent switching mechanism arranged in said housing. An insulating film is arranged between the lower part and cover part, which insulating film extends with its peripheral region onto the upper side of the cover part. The wall of the lower part is bent onto the upper side and thus holds the cover part on the peripheral shoulder with the insulating film interposed. Said temperature-dependent switching mechanism, depending on its temperature, produces or opens an electrically conductive connection between two contact areas provided externally on the housing. The cover part exerts a radially outwardly directed pressure onto the inner side of the wall via the insulating film. | 01-28-2016 |
