A Way To Repair A Broken Switch On Ferret Finder

[Arry 21,517]

The little screw is 10ba thread mostly used in electrical gear.

Looks like you can get them from this site http://www.ba-bolts.co.uk/steelrnd.html

 

supplies model engineers. Sorry its not a link not sure how to do that, but copy and paste the address into google think that will do the same thing.

 

I think the screw was 17p

The Link did not work from the post but copy and paste will work.

Is there no where you can buy a new thumb wheel/switch

[Arry 21,517]

Not sure if those are the right value. I bought a few off ebay though on the ferret finder page, Fitted a few now and they do work. Some times its worth cleaning that switch by take the yellow disc carefully off ( which is under there wheel )and use a cotton bud and some electrical cleaning fluid or some mentholated spirt might do it.

 

If you are getting a lot of interference its usually that switch.

On those it has B5K written on them which probably means 5K ohms = 5000 ohms I think, I'm no expert though.

 

Cheers Arry.

[maxwell 88]

Cant see any difference between the two if they are both 5k ohms

[Arry 21,517]

I think they are 50k ohms which = 50000ohms

 

And the if B5K (which is printed on the replacements I bought and I know they work) means 5K ohms = 5000ohms. K = 1000

 

B5K is all I had to go on and I can't find any think on line with those numbers.

 

I'm no expert though but I've fitted 3 in different boxes they all work now.

Good fix mate thanks for sharing with us.

 

Does anybody have or know where I can get the trimer resistor that has 100 written on it. it is a adjustable resistor there are 2 on the board and are different values, these adjust the distance but it is tricky.

 

Cheers Arry

 

The size of the timmers are 100R and 1M.

 

1M are readily available and cheap

100R are harder to find and dearer
