Agilent 53131a Switch
« on: June 12, 2015, 06:06:24 am »
Hello Everybody,

I was in the process of installing the 3Ghz option in my 53131a frequency counter and noticed some little white pieces floating around the front panel so I decided to open it up and see what it was from. As you can see in the picture it looks like the button appears to be toast as the little clips that hold the switch together have broken off.  Does anyone have any idea where I can pick up a new button?



Any help would be greatly appreciated.

You can also order them directly from Keysight.
I have ordered many original knobs and switches from Keysight in the past, when I could not find them anywhere else.
Keysight has a website for selecting parts:

There are 3 kinds of people in this world, those who can count and those who can not.

Thanks for the reply's I will take a look. If anyone has any ideas on part numbers please let me know.  The only numbers on the switch are 9734 and 201 and the first one looks like a date code to me.

Thank again,

You could try something radical like look up the part number in the service manual which is easy to find on the net.

haha, thanks   :P  That was the first thing I did but all I could find was the part number for the entire front panel assembly.

Why don't you just order this part as spare part from keysight?


 :scared:  Could not get that link to the keysight website to work ...

So, at their site, look for parts, enter the part number and you will find it orderable ..

Yep, that is what I did. 

Here is the link to the part below.

I also believe you could order the part from here but I have not verified this I am just going off the mfg. part number.

Good to see that. They look almost like the ones in the Tektronix differential probes. Had to disassemble and fix them. I was not able to find the damn things. Replacement would be more reliable.

Yeah they look almost identical to the ones in your probes.
