Description: We use barrel jacks a lot around here and sometimes we need to pop a switch into the mix. That usually means hacking up a perfectly good barrel jack extension cable, but the whole point of using the barrel jacks was so that we wouldn't have to hack things apart... Well, we found a solution: The Barrel Jack Power Switch.

Okay, it's nothing fancy but it is really useful. Plug your power supply into one end and the other into your project and, just like that, you've got a power switch! The on-off rocker switch has a good stiff 'click' to it, so it isn't easy to accidentally switch. It's also fairly small so it won't add too much unnecessary bulk to your project.

Dimensions:

  • Switch Body: ≈ 61 x 27 x 23mm
  • Cable: 85mm long (each side)
  • Barrel Connector: 5.5x2.1mm

  • What size barrel connector does this have?

  • I’ve had this switch for about 7 months on an Arduiso Uno. 12-15 cycles p/day. No problems yet.

  • The barrel size is actually 2.1mm. The switch is rated at 2A; it’s equivalent to COM-11477 except it’s a little wider. Did I say the barrel size is 2.1mm? Yep, it’s 2.1mm, unless they happen to send you one that’s 2.5mm.

  • Is there a reason you used a bigger switch than your Lamp Switch COM-11477? Is the switch used in this product available for purchase individually?

  • Maybe a similar thing but for a USB cable? I always find them more of a hassle than barrel jacks.

  • Can it handle the output from a 12V car battery or 7Ahr Battery?

  • is it a 2.1/5.5mm?

    • It is indeed. We use that size a lot! Thanks for pointing that out, I added it to the description.
