Safety selector for a firearm

A safety selector for a firearm, comprising:

• a first lever, a securing element, and a connecting assembly;
• wherein:
• the first lever includes a first handle and an integrally-formed safety shaft, and is configured for a spring-biased coupling to the securing element;
• wherein:
• the safety shaft is configured to be received in a lower receiver of the firearm and to be rotatable into at least one firing selection position, and includes a first, substantially cylindrical bearing portion joined to the first handle in a direction toward an opposite weapon side, a selector portion formed adjacent to the bearing portion and having at least one primary selector surface, and a connecting portion adjacent to the selector portion;
• the first handle is configured to be outside the lower receiver for actuation of the safety selector when the safety shaft is received in the lower receiver;
• the securing element includes a substantially cylindrical bearing protrusion for mounting in the lower receiver, the bearing protrusion having in a circumferential direction a primary cam configured to interact with a selector pin disposed in the lower receiver, where the primary cam also defines a mounting groove that is directed toward a weapon midplane;
• the connecting assembly includes a connecting element, a spring, and a spring lock;
• the connecting element being configured at a first end for coupling to the spring lock and configured at its opposite, second end for coupling to the securing element;
• wherein:
• the first lever has, on the connecting portion of the safety shaft, a positioning protrusion projecting in a direction toward the opposite weapon side, and, in a longitudinal direction, a bore of complementary shape for receiving the connecting assembly;
• and
• the bearing protrusion defines a coupling recess that opens outwardly in a radial direction and in the longitudinal direction and is configured to couple to the second end of the connecting element and the positioning protrusion.
