1
00:00:00,160 --> 00:00:07,680
quick response times tactile feedback that delightful clickity-clack sound

2
00:00:05,520 --> 00:00:12,160
that's like a vegas craps table that keeps your roommate awake at night

3
00:00:09,679 --> 00:00:17,279
mechanical keyboards are awesome for all of that not to mention their durability

4
00:00:14,320 --> 00:00:24,160
and premium feel but what if instead of relying solely on a mechanical actuator

5
00:00:20,320 --> 00:00:25,439
you could harness the power of light

6
00:00:24,160 --> 00:00:30,400
when you type and i'm not talking about the ever

7
00:00:27,199 --> 00:00:31,920
present RGB backlighting either we are

8
00:00:30,400 --> 00:00:37,600
starting to see optical keyboard switches hit the market

9
00:00:35,040 --> 00:00:43,600
which are actually sort of a fusion of existing mechanical keyboard technology

10
00:00:40,320 --> 00:00:45,920
and infrared light that determines when

11
00:00:43,600 --> 00:00:51,120
you push down on a key and unlike the huge variety of purely

12
00:00:48,879 --> 00:00:55,520
mechanical switches there are only two main types of optical switches out there

13
00:00:53,280 --> 00:00:58,800
right now since the technology is rather new

14
00:00:56,399 --> 00:01:04,320
the first type is called a light strike switch also called an lk switch these

15
00:01:02,079 --> 00:01:10,560
work with a more or less traditional mechanical shaft that blocks a freaking

16
00:01:07,600 --> 00:01:14,560
infrared laser beam when it's idle but when you press down the beam is allowed

17
00:01:12,880 --> 00:01:19,600
to hit a sensor on the other side of the switch which registers a key press

18
00:01:17,439 --> 00:01:24,080
now although this is a pretty simple principle of operation it actually

19
00:01:21,680 --> 00:01:28,880
allows for faster response times when gaming because lk switches register

20
00:01:26,560 --> 00:01:33,360
keystrokes after traveling just one and a half millimeters downward about 25

21
00:01:31,680 --> 00:01:38,479
percent less than most current mechanical keyboards the manufacturer

22
00:01:35,840 --> 00:01:42,720
also claims that actual response times could be as low as a fifth of one

23
00:01:40,560 --> 00:01:46,720
millisecond which is useful if you need to aim and fire quickly before getting

24
00:01:45,200 --> 00:01:50,320
headshotted not that too many people have firebound to their keyboard don't

25
00:01:48,399 --> 00:01:55,600
worry about those little details the other kind of switch goes by the

26
00:01:52,159 --> 00:01:58,000
super intense name of flaretech

27
00:01:55,600 --> 00:02:04,799
and works quite differently instead of using a beam of infrared light the pcb

28
00:02:01,280 --> 00:02:06,719
has an upward facing ir sensor that can

29
00:02:04,799 --> 00:02:11,280
tell when the switch itself is being pushed down now although this is a

30
00:02:08,800 --> 00:02:16,800
little more complicated and expensive to engineer than the lk switch the ir

31
00:02:14,000 --> 00:02:21,280
sensor can actually tell how far the switch is being pressed down allowing

32
00:02:18,800 --> 00:02:26,560
keyboard manufacturers to use them as so-called analog switches in fact a

33
00:02:24,560 --> 00:02:30,160
dutch keyboard manufacturer called wooting

34
00:02:27,840 --> 00:02:35,599
currently has a keyboard with flair tech switches on kickstarter featuring this

35
00:02:33,120 --> 00:02:40,879
analog control that they're advertising as fine control over things like player

36
00:02:38,480 --> 00:02:45,280
movement or steering and throttle in driving games imagine being able to push

37
00:02:43,360 --> 00:02:49,840
down just a little bit on a key to make your car go more slowly around corners

38
00:02:47,920 --> 00:02:54,720
instead of like spamming the key and hoping that somewhere between here and

39
00:02:51,599 --> 00:02:57,560
here is like like here ish

40
00:02:54,720 --> 00:03:02,080
cool right looting is also pushing customizability as a feature of this

41
00:02:59,840 --> 00:03:06,159
keyboard as the analog functionality can be programmed in a number of ways to

42
00:03:04,480 --> 00:03:11,040
make these keyswitches much more versatile than traditional ones

43
00:03:08,480 --> 00:03:15,760
and i mean beyond just gaming they also have the distinct advantage of being

44
00:03:12,800 --> 00:03:20,239
replaceable since neither type has to be soldered onto the pcb

45
00:03:17,760 --> 00:03:25,360
so the light sensor used by an lk switch is housed in the switch itself while the

46
00:03:22,319 --> 00:03:27,680
ir sensor of a flaretech switch doesn't

47
00:03:25,360 --> 00:03:32,799
need a physical connection to the switch making combining like a keyboard base

48
00:03:30,319 --> 00:03:37,519
plate with any other type of mechanical actuator that you want

49
00:03:34,799 --> 00:03:41,760
sound pretty versatile in the future and all of this without giving yourself a

50
00:03:39,040 --> 00:03:47,040
crash course in soldering of course since the technology is so new

51
00:03:44,640 --> 00:03:51,280
there isn't much to choose from yet although there are a small handful of lk

52
00:03:49,120 --> 00:03:55,360
switches currently available on amazon but given their potential to help gamers

53
00:03:53,440 --> 00:03:59,519
get quicker response times and more granular control it wouldn't be

54
00:03:57,360 --> 00:04:03,120
surprising to me to see bigger name peripheral brands try to incorporate

55
00:04:01,439 --> 00:04:08,799
optical switches into their keyboards in the near future and bring in the sweet

56
00:04:05,840 --> 00:04:13,680
