ABSTRACT:
A switch mechanism for a flashlight is disposed in an end cap on a rear end of the flashlight. The switch mechanism includes a plunger cylinder fitted within the end cap, an annular ring being force-fitted on a front end of the plunger cylinder, a guide with a number of guide blocks and a cam surface being slidable in the plunger cylinder, a plunger with a number of ribs and a cam surface being slidable in the guide, a contact element passing through the annular ring, and a spring being biased between a rearmost battery and the contact element. The contact element is pushed to overcome a biasing force of the spring and is contactable with the annular ring by depressing the guide.
