Sean McCauley is the founder of Cloud Defensive. His first product was developed to solve a problem with the Surefire tape switch when used with Surefire weaponlights. I will be honest, I don’t use tape switches because of the problems that the have.
The tapeswitch in question is the ST07. It is the classic tape switch that comes with Scoutlights and Millennium Weapon Lights. Surefire bundles them with an alcoholic wipe and adhesive velcro. For many people this is good enough. However the velcro creates a buffer zone due to the design of velcro. As you push the tape switch, that is attached by velcro, you need to over come the squishiness of the velcro before you can actually press the tape switch to activate the light.
Another problem is the actual cable. While the 7 in ST07 refers to the length of the cable and it is generally plentiful for most needs, it does just hang about. Some people have resorted to using zip ties or some type of cable management that is not entirely rugged to abuse.
So to address these problems, Sean created the Light Control System or LCS. It is a machined piece of aluminum that clamps the ST07 to a picatinny rail. Is has integrated cable management. Now the LCS, at first glance, looks bulky. But it only adds 1/8″ to the height of the ST07. The protective housing is what looks bulky.
You can see in the photo below just how low profile the LCS actually is.
Here is a video by Sean McCauley talking about the LCS.
The torture test is very clear in showing how robust the LCS is. It keeps the tape switch in position and protects it.
Surefire does make the SR07 which is a rubber molded rail clamp tape switch. It works but still suffers from being easily ripped off if caught on something. The LCS solves this issue as you can see in the video above.
At the moment, they only make the LCS for the STo7 tape switch. From their research, the Surefire Tape switch is the best on the market. Pretty much any place on the switch can be pressed to activate the light. That is not the case for other tape switches, even from reputable defense companies.
The LCS retails for $60 and can be purchased on CloudDefensive.com
