A close look at the sliding contacts in a cordless appliance base.

The place these things are most used in the UK is in kettles for boiling water. You basically have a jug that you can fill with water and then place onto a base that makes the electrical connection to heat the water.
This module also has a thermal switch mechanism. I'm not sure if it's to regulate a product at a specific temperature or if it's a safety feature in case something overheats.
I'm guessing that the weight required to properly mate the connectors may also dictate the minimum liquid level in a kettle when using it.

Here's a link to an eBay search for this type of connector. Target price around £2/$3.

The middle pin is earth/ground. I wouldn't recommend using this for high current use even if it is designed as a kettle connector.
