AI Technical Summary

Problems solved by technology

At present, in the multi-turn output switch operating mechanism, the transmission system at the output end is mixed with the transmission system of the inductive element, which makes the switch operating mechanism must include a deceleration part that decelerates to less than one turn, and needs to be accelerated again. The speed-up part of the multi-turn output is realized, which makes the transmission system of the switch operating mechanism of the multi-turn output more complicated. At the same time, in order to meet the requirements of the transmission strength, the deceleration part also needs to be designed with a higher strength (higher than the actual demand of the switch to be operated. ), resulting in a higher production cost of the switch actuator for the entire multi-turn output
