    Great for repair many kind of small devices like garage or car remotes......carradios...or maybe printer boards....Seem reliable, very small surface mount switches good click feel to them, kinda fun to smash the bag of them in your hand, like popping bubble wrap that self heals!Its easy for solder....use it almoust every day... great price for 100 peaces...nice for people who use it in electronics....
    Nothing...
    You should buy it never know when you need this one...;)
  • Very Nice Item

    posted by MRXC90

    Reasonable price. If your looking for a Constant voltage power supply? this is certainly not a bad deal. It does what it states. Also interesting to know is you it has a dial on it so you can adjust the voltage down to approx. 11.1 Volt. Seems rather unimportant, but it often is useful to limit voltage a little bit lower than 12 volt. The same way you can beef it up to +13V if you ever want to challenge your LED's ;-)
    Be aware it isn't waterproof (obviously, but never the less). Although it's pretty good caged and shielded, one must be aware that 12Volt and 220V are sitting pretty damn close to eachother. A mistake is easily made. Better would be to have them separated at different sides.
    Does what it should do. Deliver a constant 12 Volt.
  • I'm using this 5mts led strip to light up my pond

    - really waterproof* !!!
    - the power supply seams to be strong enough
    - the strip light is really strong (see the images uploaded - when approved)
    - the strip is alive after 3 days 25cm under water (after a silicone work on it's start and end)
    could inform us how deep can we use it
    could have a better finishing on start and end edges
    could have a longer wire on it... I have to join the wires under water... with more silicon work hehehe
    but you can change the wire with some solder work...
    5mts led strip with very good amount of light, with low power consumption, and waterproof (almost, but easy to get it perfectly with silicone) with an accessible price!! buy it !!
  • Works as expected

    Works as expected, good quality. I ordered it for a LED stripe. Even a non electrician as I can figure out where the cables go.
    For about the same price, I can get a PS for a PC rated 350W. I am not able to compare the qualities of both, but I should have considered this alternative. A PC PS has more parts, so I would expect a lower price here, but as I already said, I am not an electrician.
    Well, as I already mentioned, the PS for a PC might be a better deal.
  • The same as any other tact switch, but cheaper

    posted by pfriedel

    Unlike other tact switches I've owned, these slip right into a 4x3 array on a breadboard without having to fiddle with the tabs too much. Clear definite click, as well.
    If you're looking for buttons for a project, these will do nicely.
