5. When the button switch is used in high temperature situation, it is easy to cause plastic deformation and aging and loosening, resulting in short-circuit between connection screw. Insulating plastic pipe can be added at connection screw to prevent short-circuit.

6. Button with indicator lamp is easy to deform plastic lampshade because of bulb heating. It should reduce bulb voltage and prolong service life.

7. "Stop" button switch must be red; "Stop" button switch must be red mushroom head type; "Start" button must have a protective ring, the protective ring should be higher than the button head, in order to prevent accidental touch to make electrical equipment malfunction.
