Stress Tests

Due to the high quality of material and increased design complexity, a rigorous lab testing process was instilled. Weatherization: sub-zero temperature of -20C for 48 hours. Heat-stressed at 70c for 48 hours.

Temperature Fluctuations: five repeated cycles of temperature fluctuating between 20c, -20c, 20c, 70c (1 hour each)
Humidity: 48 hours, with 90-95% relative humidity at 60c.

In the spirit of SwitchCaptain and the Deep Blue naming of this switch, the Kailh lab also sprayed the switches with salt water for 12 hours straight at 35c. No corrosion, no cracks, no exposed base plates.

For those DIYers soldering the switch, we ensured no abnormalities at soldering temperatures of 260c were present at 3-second intervals. The switch can handle 350c soldering temperature at 3-second intervals and will ensure a 95% surface area solder immersion.

*Sound Testing Specifications

Meter: BK2550-L

Dongguan Kaihua Electronics Co., known in the USA as Kailh, is a manufacturer of top-of-the-line mechanical keyboard switches and is famous in particular for their box switches.

All BOX Silent Brown switches are ordered directly from Kailh, tested in the US by SwitchCaptain, and packaged in sets. 

What is the SwitchCaptain Authentication program?

We are keyboard and mice enthusiasts ourselves, we have spent hours (perhaps days, okay fine, weeks) trying to find particular keycaps, switches, lubricants, and more. Too often we stumble across knock-off products, poor quality components (that can do real damage), and sometimes even stores passing non-genuine products as the real thing! Enough is enough. So we got together and decided on a plan moving forward to stop fake products from hurting all the different folks involved.

The SwitchCaptain Authentication program includes a holographic seal on every item we sell, each seal has a unique code that lets you verify your product came from the original brand. 

We want you to know that if you buy a product from us that what you get is real. 

Let us be clear:

• All branded products we sell are bought from the manufacturer directly, we do not try to save a buck and purchase from a supplier (which we find super suspicious in the first place). If a manufacturer won't sell to us direct we will not have it in the store. This includes big names as well as up-and-comers. 
• This also means that manufacturers ship directly to us, we inspect for quality, package them in sealed bags (so they cannot be tainted), code them into our authentication database, and ship it to the customer (that's you!). We do not allow 'middle-persons' to broker any product, as this opens up an opportunity for manipulation.
• Any product from SwitchCaptain without an authentication sticker is counterfeit or repurposed without authorization. Even our refurbished products are authorized.
• We require all brands to provide us with proof of any certifications they say they have. The onus is still on them of course. If a manufacturer cannot produce for example their RoHS (Restriction of Hazardous Substances Directive) when they are supposed to be able to, we will not work with them. While we do not know of all licenses, permits, and certifications, we try our best to keep an eye out.
