A battery interrupter is a simple, affordable 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.
This device is a battery interrupter based on a flexible PCB with a mono/stereo 3.5 mm audio jack.
The original design was created by Dale Grover which is called Flex_Battery_Interrupter_200.
The shorter model was created to offer an even more affordable option which is called Flex_Battery_Interrupter_100.
The difference between the two models is simply the length of the battery interrupter.
The design files for the two models are available and can be found using following links:
- Flex_Battery_Interrupter_100 (100 mm x 34 mm)
- Flex_Battery_Interrupter_200 (203.3 mm x 34.3 mm)
Flex_Battery_Interrupter_Jack_Case provides additional support for both Flex PCB and the 3.5mm jack.

- Flex_Battery_Interrupter_200 (203.3 mm x 34.3 mm)
The main component of Flex Battery Interrupter is a 3.5mm Stereo Jack which is listed in Flex_Battery_Interrupter_BOM.
Dale Grover contributed to the inital idea and design of the battery interrupter using a flexible PCB.
The PCB, 3D printable jack enclosure, and all documentation was completed by Makers Making Change.
