On-off transmission device for high voltage electric switch
The present invention provides a novel on-off transmission device for high voltage electric switch, comprising conducting rod and switch actuating device to actuate the reciprocating motion of the conducting rod, wherein an insulation layer is coated on the circumferential wall of the conducting rod. An insulation main shaft and an insulation crank arm rotate and swing to actuate the linear reciprocating motion of the conducting rod, and the contact compressing spring sheet is directly applied to the externally insulated conducting rod. Besides, the insulation portion is directly provided outside the conducting rod, which not only cuts down the cost of production, but also makes the overall structure compacted, simplified and miniaturized, and detachment and maintenance become more convenient.
