Customer Comments

  • It’s worth noting that in order to mount the button, the switch will first have to be removed from the assembly. This is best accomplished by using a small screwdriver to pry back a plastic tab that has a knob that fits in a hole of the actual switch. The switch can then be rotated and the other knob comes out much more easily.

  • I like the fact that this is a SPDT switch: that way you don’t need pull-up or pull-down resistors, just connect the common to the input and the other two to 0V and VCC

    • Especially if you’re connecting to anything CMOS, you really still should use them. Otherwise, the input gates are left flapping in the electric wind during the travel time of the switch. Might not be a big issue with BJT devices, though.

  • Feels a bit cheap, but looks nice. Does the job.

  • Can someone give me an idea of how much bounce to expect from this switch? I’ve only ever used breadboard push button switches before. Would something like this be appropriate?

      boolean ButtonRead = digitalRead(ButtonPin);
      if (ButtonRead == true)
       boolean ButtonRead2 = digitalRead(ButtonPin);
       if (ButtonRead2 == true)
         //Code to be executed when button is pushed
  • I bought this to use with el wire, but when I put this between my inverter and the el wire the inverter no longer works as if it thinks there is a short somewhere. Any idea why this would be happening?

    • You should be turning off the inverter, not the wire

    • Although the Button is rated for AC current there’s probably more than 3 Amp going through it. The button is probably dead but that still doesn’t explain the dead inverter.

  • Love the action! Want other colors. Don’t make me order elsewhere!

  • While these guys are a bit more expensive then the 33mm convex ones sold here, they’re actually a pretty good deal when you consider the fact that the microswitch included with them is over ¾ the price. You only paying $0.45 more for the nifty arcade button.

Great buttons

These buttons have a nice mechanical feedback, feel solid and look good. Will buy again.
