1. A power line vacuum switch comprising:
a vacuum bottle switch that includes a fixed electrical contact and a dynamic electrical contact;
a switch actuator that includes an open/close circuit linkage that is connected to the dynamic electrical contact via a dynamic contact shaft and a shock absorber assembly,
the shock absorber assembly comprising a housing defined by at least one housing side wall that extends from a base to a housing top, the at least one housing side wall fixedly connected to the base and housing top, the housing top comprising a shock absorber housing port,
a coil spring disposed inside of the housing and connected to the base,
the open/close circuit linkage connected to the base outside of the housing,
the power line vacuum switch comprising an open orientation with the dynamic electrical contact separated from the fixed electrical contact and with the coil spring in an uncompressed state, in the open orientation, the housing is in a first position;
the power line vacuum switch comprising a closed orientation with the dynamic electrical contact connected to the fixed electrical contact and the housing in a second position, the housing is closer to the fixed electrical contact in the second position than when in the first position,
when in the closed orientation, the coil spring is in a compressed state,
the open/close circuit linkage spaced closer to the fixed electrical contact in the closed orientation as compared to the open orientation,
the coil spring, the base, the fixed electrical contact, the dynamic electrical contact, and the shock absorber housing port are symmetric about an axis.
