My Unimax laser is mounted on top of an extended rail in front of the front sight post of my AR-15. This is a perfect mounting position for me, but the standard mechanical switch was virtually impossible to manipulate smoothly and effectively. The momentary switch solved the problem and allows easy activation/deactivation when I need it. The 6" cord is just the one that best fit my application.
Pros: Eliminates the cumbersome mechanical switch
Cons: None
