Microswitch for main gear TB20

Is there anyone who has an idea where can I get

a microswitch (MS) TB 20 main gear right, called end of travel.

This MS informs the pilot that the gear is up, and the transition light ( red) goes off.

Look here under Landing Gear Switches.

You need electrical / wiring expertise to do this, whereas if you bought the whole assembly (the switch and the cable+connector) from Socata for 2x to 4x the price you would not need to do anything and any “mechanic” can do it.

Hi Peter.
Thanks for the prompt help and alternative . For now I have repaired this MS. I’m again and yet again shocked about the price.

Hi All,
With the help of Peter’s part list, I have identified the right Crouzet microswitch for the end of travel.
However the minimum ordering quantity is 100 pcs, and no distributor (contacted 5) wants to send me 3 pcs only.

Any idea where could I buy those?
If I am not mistaken this is the variant:
83139 Series, 831391 IB S0.5 139EX R28.7

LHFM, LHTL, Hungary

RS do similar if not identical variants; I bought some from there. Different wires / connector but that’s easy.
