Can you provide anything more about the R135-Series?

I am an engineer, and I am a new one in this field. I have known some characteristics about R135-Series rotary switches.

The R135-Series rotary switches are AC/DC rated single pole, single throw switches. They are 'L' rated up to 3A, and feature an On-Off repeating action.

They are available with a black or white nylon actuating knob, nylon snap-in bracket or nickel plated brass bushing.

Anyone who knows more about it?
