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.

## Description

Sparkfun use barrel jacks a lot around here and sometimes Sparkfun 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 Sparkfun wouldn’t have to hack things apart… Well, Sparkfun 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
