If a saw is used to replace the drilling and chiseling method, the installation positioning line of the electrical indicator lamp switch needs to be drawn on the electrical equipment box first, and then the steel plate is cut along the installation positioning line of the electrical indicator lamp switch using a saw. After the steel plate is cut off, the frame is smoothed and trimmed with a file, burrs are removed, and finally the indicator lamp switch is installed in place. This construction process is complicated, inefficient, and cannot be batched, with low opening hole precision. SUMMARY
