Claim:
1. A reversible safety selector switch for a firearm, comprising: a control shaft pivotably mountable about an axis in a lower receiver, the shaft having a cam portion, the cam portion having first and second recessed faces and a remainder of the cam portion being a substantially uninterrupted trigger movement blocking cam surface, and a hub portion having at least one substantially cylindrical surface and first and second detent grooves with detent sockets at each end of each groove, the first detent groove extending circumferentially approximately 90 degrees along at least one substantially cylindrical surface of the hub portion and the second detent groove extending circumferentially less than 90 degrees along at least one substantially cylindrical surface of the hub portion; and a control lever connectable to an end of the control shaft and configured for manipulation outside the receiver by a user to axially rotate the control shaft, wherein, when the selector is installed in the receiver, a detent pin in the receiver engages a selected one of the detent grooves and prevents axial rotation beyond a detent socket, the first cam portion face and first detent groove being positioned to allow axial rotation of the shaft only between safe and fire positions in approximately 90 degrees of rotation when installed with the detent pin engaging the first detent groove and the second cam portion face and second detent groove being positioned to allow axial rotation of the shaft only between safe and fire positions in less than 90 degrees of rotation when installed with the detent pin engaging the second detent groove.
