Battery Interrupter for Switch Adapting

It was recently brought to our attention that we don’t have a design for a battery interrupter on the website.

A battery interrupt / battery interrupter is a simple, cheap device that enables you to switch adapt many battery powered electronics devices and toys. The battery interrupt is slipped in between the batteries or battery and battery terminal, breaking the circuit until a switch is attached and closed.

MMC had previously put together a set of instructions for creating one using copper tape and a switch jack:

Does anyone else have a favorite design or technique they would like to share?
e.g. There is a similar solder-free version here: https://www.instructables.com/No-Solder-Battery-Interrupter/

Maker Works which hosts our program is developing a variety of products which are intended to make AT simpler and more affordable. One is an inexpensive solder free jack for switch adapting items that uses a custom printed circuit board and screw terminals for attaching the wires. Used in conjunction with WAGO 221 Series LEVER-NUTS a device could be switch adapted without soldering. While more involved than a battery interrupter the finished product should be more durable.

That’s very cool, and could certainly be used with a battery interrupter or to directly switch adapt a device.

Do you know where they intend to sell them? And is there an intention to release the design open-source?

If the design files are available, it would be fairly easy to create a 3d printable enclosure for this, too.

Dale Grover, the inventor, is a gifted electrical engineer with a background in AT communication devices. I saw a prototype Switch Modifier before the pandemic but only recently saw the other items in development. He designed a compact solid state switch modifier using a custom circuit board and code. Initially it had a 3D printed case but Dale is currently working on injection molded cases so the device can be economically produced at scale. The result is a product that has the features of the MMC Switch Modifier with a lower component cost, quicker production and smaller form factor.

I honestly don’t know Dale’s plans for distribution but his goal is to help as many people as possible by making the items low cost and user friendly. It would probably be best if you or someone else from MMC talked to him directly. He is looking for some people to test the products and provide feedback. If you let me know who would be the best contact I will work on arranging an introduction.

This is pretty great @brentcourson! Would love to chat with Dale and his plans… is he here on the forum? Otherwise feel free to email me - chadl@neilsquire.ca

@chadl Dale is not on the forum but I will connect you by email. I look forward to hearing what comes out of the discussion.
