A fire control switch for a firearm includes a lever assembly mounted to a first end or to a second end of a shaft. The lever assembly includes a spring-loaded rotatable pawl moveable between a first position and a second position, wherein the lever assembly is mounted to the shaft when the pawl is in the first position and can be released from the shaft by moving the pawl from the first position to the second position. In other embodiments, a second lever assembly or cap may be mounted to the other end of the shaft.
