Patent ID: 8650790

Claim:
A lockable safety selector switch configured to replace a manufacturer's original safety selector switch for a firearm having a selector detent pin, the lockable safety selector switch comprising: a. a body configured to selectively rotate about an axis in the firearm directly between a SAFE position that prevents the firearm from firing and a FIRE position that allows the firearm to fire the body defining an opening in an outer surface of the body to receive at least a portion of the selector detent pin when the lockable safety selector switch is positioned within the firearm; b. a locking mechanism comprising a rotatable cam housed at least in part within the body, the cam engaging and selectively allowing at least a portion of the selector detent pin to enter the opening in the body to prevent rotation of the body and thereby lock the body in the SAFE position, the cam further configured to rotate within the body to selectively urge the selector detent in out of the opening in the body to allow rotation of the body out of the SAFE position and thereby unlock the body, the cam having a cam interlock element; c. a body interlock element positioned on the body to operatively engage with the cam interlock element, the body interlock element being complementary to the cam interlock element; and d. a biasing member operatively associated with the cam, the biasing member urging the cam interlock element into engagement with the body interlock element such that when the complimentary interlock elements are engaged with each other, the cam is substantially prevented from rotating within the body; wherein the lockable safety selector switch is configured such that the firearm requires no modification in order for the lockable safety selector switch to replace the original safety selector switch and operate to lock and unlock the switch.
