Looking for Wireless Controlled On/Off Switch for Headtorch?

Hi

Basically, I’m trying to create my own version of a Bontrager Ion RT which is controlled using the ANT+ protocol, but lighter, and a tighter throw.

I’m trying to find the suitable parts, primarily of concern is the the switching mechanism, looking to replace switch & pill that’s in an existing body rather than building everything up from scratch.

Has anyone seen similar parts anywhere?

I want:
Simple, Wirelessly controlled remote On/Off,
Hardware override “complete off” functionality.

Any ideas greatly appreciated.

I was looking at remote momentary switches like this for a bit. Haven’t revisited the idea though.

Look at this on eBay:
