Brompton SP / Shimano hub dynamo connector
The Brompton SP / Shimano hub dynamo connector looks like a very small Lego brick, and connects to either the (new for 2019 model) SP - Shutter Products - and the the Shimano hub dynamo. Occasionally they have been known to work loose and fall off - which is why we offer this spare part!
Compatible with both SP and Shimano hub dynamos
It can also be used on a non-Brompton Nexus Shimano hub dynamo if you have lost yours.
It can also be used to connect other (non Brompton) lights to the Brompton Shimano wheel.
Section 3c of the download document shows how it works.
The main picture shows the tab connector open with the two dynamo wires inserted (which wire goes into which side is not important)
