In a force waveform of an assembled body having an elastic component assembled thereto, in order to specify a deformation start point or a deformation end point of the elastic component as easily as possible, an inspecting device includes: a force-waveform detection system that applies a load to a workpiece having an elastic component in the direction of action of the elastic component and acquires a force waveform; an inspection-parameter designation unit that acts as reception unit in order to receive an input of an arbitrary designated point during a process of deformation; and an inspection unit that calculates a local slope of the force waveform at the designated point, thereby specifying, on the basis of the local slope at the calculated designated point, a physical characteristic change point including the deformation start point or the deformation end point.

A relay and a method for indicating a relay failure may be provided, whereby the relay comprises a switch assembly capable of providing a trigger signal based on a switching status; an energisation element capable of energisation to affect the switch assembly; and a light indication for indicating a switching status of the switch assembly.

A microelectromechanical systems (MEMS) switch device including current sensing and overcurrent protection can include a movable plate movable between an open position and a closed position, wherein the moveable plate is moved by applying at least one or more of an electrostatic force and a magnetic force to move the movable plate. The movable plate can include a shunt operable to conduct current when the movable plate is the closed position. An inductive coil electronically coupled to the shunt can detect current conducted through the shunt.

Exemplary embodiments are disclosed that include multi-voltage contactors, controls, and related methods.

An electromagnetic relay includes a case having an accommodating space that is open to an outside through an opening, and a base fitted into the case and closing the opening. The case or the base has a flame extinguishing hole for extinguishing a flame. The accommodating space accommodates a coil, a pair of fixed contactors and a movable contactor, and communicates with the outside through the flame extinguishing hole. A sealing member covers the flame extinguishing hole to make the accommodating space a sealed space and suppress intrusion of gas from the outside to an inside of the accommodating space. A moisture-absorbing member is arranged in the accommodating space to absorb water vapor within the accommodating space.
