Definitions

  • the present invention relates to the technical field of switches, in particular to an isolating switch.
  • the base assembly comprises two base frames, two linkage plates and a support; the support is installed between the two base frames; a first rotary shaft and a second rotary shaft are provided on the support so as to be spaced apart; the two linkage plates are installed on two sides of the support by means of the first rotary shaft; the two linkage plates are connected to the rear conductive arm; the drive shaft is connected to the second rotary shaft.
  • the base assembly further comprises a support plate and a limiter; the support plate spans the two base frames; the limiter is disposed on the support plate and located between the support plate and the rear conductive arm.
  • the first rotary shaft 11062 and the rotary shaft 11052 are two parallel rotation shafts.
  • the crank 1104, the connecting rod 1105, and the linkage plate 1106 on which the rotary shaft 11052 is installed together form a crank connecting rod mechanism, capable of driving the rear conductive arm 130 stably and reliably.
  • the front conductive arm 150 comprises a pipe element 1501, two connecting portions 1502, multiple contact fingers 1503 and a protective cover 1504.
