A pressure-actuated switch having a pressure port, a diaphragm, a range spring, an actuator plate, a differential plate, and an electrical switch. A certain pressure level moves the diaphragm against the range spring at the pressure port and thus deflects the actuator plate. The actuator plate is coupled to the electrical switch via a snap spring, wherein the electrical switch can be switched on or off via the deflection of the actuator plate and the snap spring. The differential plate controlled by a differential spring is connected to the actuator plate and supports the actuator plate in a first portion of movement, wherein the differential plate is decoupled from the actuator plate in a second portion of movement of the actuator plate.

In a case made of resin and provided with a condensing lens through which light is transmitted, a circuit board on which a photoelectric element to be disposed at the focus position of the condensing lens is accommodated. The circuit board has a through hole through which the light having been transmitted through the condensing lens passes. Furthermore, the photoelectric element is mounted on the back face of the circuit board on the opposite side of the condensing lens and receives the light having passed through the through hole.

An electronic device includes a housing having a battery installed within. A spatial orientation detection unit installed within the housing generates signals indicative of spatial orientation of the housing. The electronic device further includes a timer circuit, and a controller. The controller is communicably coupled with the battery, the spatial orientation detection unit, and the timer circuit. The controller periodically receives signals indicative of spatial orientation of the housing through the spatial orientation detection unit. The controller periodically determines spatial orientation of the housing based on the received signals. The controller determines whether spatial orientation of the housing corresponds to particular spatial orientation profiles at particular periodic intervals, and switches on the electronic device accordingly for a pre-determined time period.

The invention relates to a torque limiting device in a torque bearing connecting structure between a gearbox and a stationary structure in a gas turbine engine, wherein the torque limiting device comprises a mechanical fuse in the connection structure comprising an at least partially circumferential weakening of the material. The invention also relates to a gas turbine engine.

A vehicle tailgate assembly includes a tailgate and a switch assembly operably connected to the tailgate. The switch assembly includes a switch structured to be actuatable by application of a load exceeding a predetermined threshold to the tailgate. The switch assembly is operably connected to a tailgate automatic opening/closing mechanism such that actuation of the switch controls operation of the mechanism to prevent execution of a command to automatically open the tailgate when the tailgate is in a fully closed condition.

A linear guideway is characterized in that it is capable of determining whether there is abnormal displacement of the return member based on the open or close of the circuit, and can output the abnormal signal immediately when the circuit is open. Compared with the conventional structure, since the present invention can be disposed only at one end of the slide block, both the number of components and assembly time can be reduced, and the diagnosis with precision and immediacy can be performed without high-deep algorithm, which can play a role of instant reminding before the linear guideway completely loses function. Therefore, the service life of the linear guideway can be known early to avoid the loss caused by the shutdown.
