Hi There,
I'm looking to get a tiny switch to power on and off a small LED being powered by a watch battery (CR 2032). The Right Angle Tactile Button seems like it would be perfect, but I'd like to know if it's suitable for that task. The battery only has two wires coming from its caddy, but the Right Angle Tactile Button seems to have four prongs. Are they compatible? Or is there a better product I should use for this task?

Thanks very much for your help.

Two of the prongs are extension of the metal case and are intended to provide a solid mount when soldered onto a PCB.
The other two prongs are connected to the actual switch contacts.
Note that this is a momentary button so that switch alone will not function to switch power on and off without further circuitry.

Hi DanV,
Thanks so much for your help. I didn't realize this was a momentary switch (it doesn't mention that on the product page), so that's a deal breaker right there.

Thanks again.
