1. A downhole system, comprising:
a housing securable to a conveyance;
a first linkage base disposed proximate a first shoulder of the housing in a collapsed position;
a second linkage base disposed proximate a second shoulder of the housing in the collapsed position, wherein the first linkage base and the second linkage base are configured to move axially along a center section of the housing in response to actuation of an actuation assembly; and
a shifting key configured to move between the collapsed position and an expanded position in response to movement of the first linkage base and the second linkage base, wherein a first end of the shifting key is secured to the first linkage base via at least one first linkage arm, and wherein a second end of the shifting key is secured to the second linkage base via at least one second linkage arm, and wherein the first linkage base is configured to contact the first shoulder of the housing, with the shifting key in the expanded position, to transfer a load on the shifting key to the housing through the first linkage arm and the first linkage base.
