Abstract In order to improve the anti-impact performance of control and protection switches, a switch structure is proposed. The dynamic characteristics of the contacts and the armature are studied, the dimensional parameters of the disc spring group are calculated, and the electromagnetic mechanism is designed and simulated using finite element modeling. The influence of external impact on the operation of the contacts and the armature is analyzed. The results show that the switch structure with disc springs replacing cylindrical spiral springs has enhanced anti-impact performance of the switch, and the improved electromagnetic mechanism also shows improved anti-impact performance. The research results can provide reference for the optimization design of anti-impact structures for control and protection switches.
