It needs neither batteries nor an electrical source -- it is powered by the muscle power of your wrist as you squeeze the handle repeatedly -- this one is a dyno torch, dynamo torch or squeeze flashlight.
It is an old Soviet design but in a 1990s Russian version. Similar flashlights exist elsewhere.
Made in Russia.
The white clasp is released and the metal handle can be "squeezed" repeatedly which works a small dynamo lighting a small incandescent bulb.
The handle is released.
From Wikipedia:
A dyno torch, dynamo torch or squeeze flashlight is a flashlight or pocket torch which stores energy in a flywheel. The user repeatedly squeezes a handle to spin a flywheel inside the flashlight, attached to a small dynamo, supplying electrical current to an incandescent bulb or light-emitting diode.
It fits snugly in the hand. You use three fingers to squeeze the handle.
It doesn't produce much light but enough to see what you are going to step into, also good at home when power fails. That's why I have two of them -- one at home, the other at my country place.
