What do you mean by electrical and sheet metal design?

Electrical design refers to the design of electrical control principle in mechatronics, including control schematic diagram and selection of electrical components. Now some small independent units assign pneumatic and hydraulic principle control to electrical design.

Sheet metal design is a part of mechanical design, including electrical button boxes, control cabinets, junction boxes, toolboxes, boxes and other thin iron products.

Electrical and sheet metal design can be explained in this way; The requirement for a boss to recruit employees must be electrical and sheet metal design, that is to say, except electrical design, all electrical button boxes, control cabinets and junction boxes will be dry, and there is no need to find a mechanical designer. On the other hand, before 1970s and 1980s, old electrical engineers could do both electrical design and sheet metal design.
