An insulating switch assembly is disclosed. The insulating switch assembly provides electrical insulation between a user and highly charged electric components by employing highly-resistive or nonconductive material. The insulating switch assembly also distances the user from the electrical components by increasing the distance from the user input device and electric components. The user of the insulating switch assembly is provided layers of electrical insulation.

The present disclosure relates to a protective relay. According to the present disclosure, the handle is fixed or separated by a lever structure rather than a gear structure, so that the user may easily fix or separate the handle to or from the outer casing. Therefore, convenience and operability of the user are improved.

A relay device includes an electronic block configured to selectively generate an electromagnetic force by means of a coil; two fixed contact point terminals at which fixed contact points are respectively installed; a movable contact point assembly having a movable contact point installed at a front end thereof, the movable contact point being fluctuated by the electromagnetic force to be contacted with or separated from the fixed contact points; and a base block configured to hold the electronic block, the fixed contact point terminals and the movable contact point assembly, which are accommodated in a cover. An entire space inside the cover is divided into two regions based on a contact surface between the fixed contact point and the fixed contact point terminal.

A contactor including a pedestal. The pedestal is of a step structure having notches in two ends. The step structure includes a first step and a second step from bottom to top and is covered with a cover body having a matched shape. A part, which protrudes out of the second step, at each of two ends of the first step, is provided with a first mounting groove in which a control terminal and a power terminal that are spaced apart from each other are mounted, and the cover body is provided with a first wiring port corresponding to the control terminal and a second wiring port corresponding to the power terminal. Each of two ends of the second step is provided with a second mounting groove in which an auxiliary terminal is mounted, and the cover body is provided with a third wiring port which corresponds to the auxiliary terminal mounted in the second mounting groove. The contactor has a simple structure, and wiring areas can be distinguished.
