(1) Protective button(push button switch): a button with protective shell, which can prevent the internal button parts from mechanical damage or people from touching the live part. Its code is h. (2) Dynamic off button(push button switch): under normal conditions, the switch contact is a button for on. (3) Dynamic closing button(push button switch): under normal […]

(1) （push button switch)Always check the button to remove dirt. Due to the small contact spacing of the button, after years of use or poor sealing, dust or oil emulsion will flow in, resulting in reduced insulation and even short circuit accidents. In this case, insulation and cleaning treatment must be carried out, and corresponding sealing […]
