rotation

I spent few hours searching for switch push button (4PDT Alternate) for Hamptone Jfet pcb based on Mnats layout.
I should get this switch:

My ussual source is Farnell. I found some switches there, but i'm not sure which would be good for my needs. Link to Farnell:

Can you help me out with this? I searched a lot with no luck. Probably because i never used switch like this before.
I don't need button with LED.

We also sell an Alps SPUJ switch which may be suitable (part number AL-03-006).

If you click on the photo it will show you more details.

Where possible these are supplied in the "service style fitting" which have bent legs to stop them dropping out of the circuit board when soldered by hand.

Yours has 12 legs, mine 14, but two are not used on the pcb. Would this work? Should i bend some legs? Which?

It has 12 legs. It is 4PDT Alternate type. The picture in catalog is just generic.

The extra 2 pins at the front will be for the LED.

Aha, thanks. I thought they are for leds, but i couldn't figure out from the pcb beacuse i only have copper layer, no parts placement. It is good learning experience...
Nice, i can start soldering  :grin:
