Waterproof 4xAA battery case with pushbutton switch

These nice battery holders are suitable for 4 x AA batteries. They are robustly made and the gasket-sealed cover is held on with four screws (which screw into captive nuts, so no plastic threads to strip).

They feature a rubber-covered pushbutton switch (push once to turn on, again to turn off) and around 140mm of flying leads.

Rated at IP65, they are best considered highly water resistant and so ideal for use in outdoor projects.
