Philmore switch forward voltage?

[Crims]

Hi,

I'm modding a saber and adding an Obi Wan Bladebuilders soundboard. I picked up a Philmore momentary switch for it and I'm trying to figure out the forward voltage and current to plug into the the calculator to see if a resistor is required - I do have a 150 ohm one handy as I was hoping to get a blue AV switch. I've posted the specs of the switch below - it looks like it can handle a lot of voltage but the operating voltage is 3v. Would I need a resistor in this case?

It's being powered by a 4 AAA battery pack - will also be using a 5v regulator to the board.

Thanks for all the knowledge on this forum, I've been reading a lot and it's very helpful.
