...do they use in toys like this? It's looks like 2 metal contacts you touch with your finger and the leds light up.
I'm sure it is some low voltage trip relay type thing but I don't know what to call it as I am trying to locate the individual switch body as a component ready to be installed with 2 leads. For sale.. if I have to I will just cannibalize done of these toys but I would like to find a source with these for sale.

It's most likely a small electronic circuit and it would almost certainly require 3 wires. (2 for power and 1 for the load)

Could be just a simple short to close the circuit being a bath toy. My daughter has a similar thing in her mermaid, just touching the contacts does nothing unless my finger is wet.

It's not really a switch, it's a Touch sensor.
