A switch device includes an actuation unit, a movable unit, a first base, and a second spring, which is a torsion coil spring that acts between the actuation unit and the movable unit. The movable unit is movable with respect to the base. The second spring applies a force to the actuation unit when the actuation unit is at a third position in a direction that is not parallel to a direction in which the torsion coil spring applies a force to the actuation unit when the actuation unit is at a fourth position.

A tailgate deactivation system. A switch includes two terminals configured to be electrically coupled to a tailgate power circuit that supplies power to at least a portion of a tailgate of a vehicle, and an actuator configured to electrically couple the two terminals in an on state to allow power to flow in the tailgate power circuit, and to electrically decouple the two terminals in an off state to inhibit power from flowing in the tailgate power circuit.

A method for predicting end-of-life for a component includes determining a baseline lifetime model for a component connected to a machine functional safety system. The component is part of a system with physical devices. The method includes monitoring environmental conditions and usage conditions of the component and modifying the baseline lifetime model based on the monitored environmental and usage conditions to produce a modified lifetime model for the component. The method includes tracking a lifetime progress of the component with respect to the modified lifetime model and sending an alert in response to lifetime progress of the component reaching a lifetime threshold associated with the modified lifetime model.

The door front edge rubber includes, in the hollow portion, a plurality of housing spaces, which accommodate the plurality of linear shape pressure sensing members, respectively. Movements of the linear shape pressure sensing members between the plurality of housing spaces are restricted by a partitioning portion.

A safety switch includes a detection unit, an output unit, an input unit; and a display unit. The detection unit is configured to detect presence or absence of abnormality. The output unit is configured to output an abnormality detection signal indicating a detection result of the presence or absence of the abnormality. The input unit is configured to input a display control signal. The display unit is configured to perform display based on the display control signal.

An elevator derailment detecting device according to the present invention detects the opened and closed states of contacts at first and second safety relays 82 and 83 (steps S1 and S2). Since a first NO contact 82b is closed, a first NC contact 82c is opened, a second NO contact 83b is closed, and a second NC contact 83c is opened, it is determined that there is no circuit failure. Then, the opened and closed state of the contactless relay 84 is detected (step S3). When the contactless relay NO contact 84b is closed and the contactless relay NC contact 84c is opened, it is determined that the counterweight 21 of the elevator 11 is in a derailed state.

A lifting column can provide optimized performance with a nut gap system that efficiently and precisely measures a nut gap during lifting operations. The nut gap system can have a rotating core onto which a nut and traveler are positioned. The nut can be separated from the traveler by a nut gap that is monitored by at least one sensor that continuously extends through the nut to access the nut gap.

An adjustable mount for an electrical device (such as a limit switch) or an optical device that includes: (a) a base adapted to be mounted to a surface; and (b) a platform coupled to and elevated above the base; where the platform includes, a top surface for seating an electrical sensor device or an optical device thereon, a through-hole approximate a first end of the top surface for receiving a first screw extending from the electrical sensor device or optical device, and an arcuate through-slot approximate a second end of the top surface opposite the first end for receiving a second screw extending from the electrical sensor device or optical device, the arcuate through-slot having a radius of curvature centered near or on the through-hole.

A non-mechanical-interfacing electronic switch or a mechanical-interfacing electronic switch are controlled to modulate between an active state and an inactive state based on electronic action. The switch includes an aperture defining an opening in a housing, and the opening defines an insertion path. A transmitter transmits a signal to a receiver along a signal path. To control the non-mechanical-interfacing electronic switch, a mechanical lockout device having a protrusion is inserted through the opening of the aperture along the insertion path. To control the mechanical-interfacing electronic switch, a mechanical control part have a protrusion is moveable to interrupt the signal. Methods of locking the non-mechanical-interfacing electronic switch with the mechanical lockout device as well as methods of locking the mechanical control part of the mechanical interfacing electronic switch with the mechanical lockout device are also provided.

Proposed are an input/output device and a control method for the same, the device including a first input/output terminal that receives a forward signal from a limit switch or outputs power to a sensor; a second input/output terminal that receives a backward signal from the limit switch or receives a sensing signal from the sensor; and an integrated circuit unit that determines a communication target for exchanging a signal through the first input/output terminal and the second input/output terminal, and selectively receives or outputs the forward signal, the backward signal, the power of the sensor and the sensing signal based on the determination result.
