Any low force microswitch for mouse?

[John D v2.0]

Hi all, just replaced a faulty microswitch in a mouse with one of these https://uk.rs-online.com/web/p/microswitches/5388771
After fitting the operating force is much higher than the original ones and it isn't comfortable.
For some reason the standard force (c farness, mouser, rapidonline) seems to be 150g/1.5N and I can't seem to locate any lighter ones.

Does anyone have any hint/pointer? It can't be that hard to find one suitable for a mouse click!

Backup plan is to swap the "left" and "wheel" click, as I hardly click the wheel so higher force will be ok. Cheers.

Is this mouse of sentimental value?

Basically exactly matches the one i linked. That one works perfectly from a physical and electrical point of view but i just found the issue with f operation force.

The one you shared is probably the same force on the actual pin, but the lever makes it lower at the end you press. Unfortunately wouldn't fit without removing the lever somehow.

Not really but it's a wireless one that suits me, so i though better to repair if it's easy enough.

Ooosp

Missed the link to the one you have.

Look at the C&K website catalogue. Low force ones are also very low current rating.

Thanks, I've had a look on the C&K (they are one of the ones sold by mouser) and there's nothing suitable. 150gm seems to be a rigid standard for some reason.

I don't know if this is relevant, but we have had three Logitech mice in which the left click button microswitches became unreliable, and they weren't cheap either!
I fixed two by opening them up and simply applying a little WD40. The third one is now showing signs of the same problem.
I think I'll avoid Logitech mice in future!

Got a sick mouse, then take it to the Vets,

( sorry )

You can often find the replacement switch on ebay etc.
Just get the details off an existing one.

What I have done in the past is remove the switch from an old mousse and reuse that, or swap the middle button for the left (usually the one to go).

Oh yes thanks for all the replies, in the end I moved the new one with the heavy click into the middle wheel, and put the original wheel one on the left click. Worked perfectly today!
