the main structure
The conducting part is mainly composed of the stylus and static contacts, the static contacts are installed on the pillar insulators at both ends, and each stylus is composed of two groove pictures. It not only increases the heat dissipation area of the stylus, which is conducive to reducing temperature rise, but also improves the mechanical strength of the stylus and the dynamic stability of the switch. One end of the stylus is installed on the static stylus through the shaft pin (bolt). The other end of the contact cutter can be separately connected with the static contact, and the contact pressure of the contact cutter is maintained by the contact spring at both ends. Base frame assembly: composed of base frame spindle and limit plate, limit plate is mainly used to ensure that the conductive contact "split" and "close" to get the required end position.
