Title: Need Source For Proximity Switches
Post by: Travelin' Man (RIP) on February 12, 2016, 12:06:40 am
I can't find a source for the small black, normally closed proximity switches that are used for the cabinet lighting.

Does anyone have a supplier?

Do you have a picture? If it is what I think it is I use those by the hundreds and can give you one.

Searching the forum fo magnetic switches ...

Can't get LED strip lights to work (http://www.foreforums.com/index.php?topic=26718.msg215914#msg215914)

After buying NO and NC switches from several place I realized that most sellers have no idea what that means.  From most sources you have a 50/50 chance of actually getting what you want. The link above references what I ended up using NO/NC depending on which wire you use. Always work.  These are small, self stick, 100% OK as delivered, never had one fail.  Shop around, they are available in multiple pack on ebay etc.  Get the ones where the white, black and gray wires come out of the end.

Amazon doesn't offer a black, normally closed proximity switch like the ones in our coaches.

Great Bill!

This switch, ZF Cherry mp201801, is listed on their web site as a NO switch.  Common definition for a NO switch says that when the magnet is brought close to the switch the contacts will close.  This means the lights controlled by the switch will be on when the door is closed.

http://www.onlinecomponents.com/zf-electronics-corp-mp201801.html?p=11075403

This is the NC version (MP201802)

http://www.onlinecomponents.com/zf-electronics-corp-mp201802.html?p=11075404

I did not see a NO/NC version.

Prices are good.

$50 minimum order, about $8 min shipping.  Still good prices.

Different manufacturers use these definitions backwards.  If you are not sure, absolutely sure, buy one and see what it does. If it does what you want then buy more.  After buying several from different sources getting different results every time, I wnet for the NC / NO combination switches. They will work in the way I want, either way, everywhere I want to use them.

I had one sales rep tell me that normally open switches are used on windows that are normally open.

Good luck with the NO switches. We are trying to be helpful here.  Are you going to tell us where you you bought your switches and the price? Thanks

Post by: Travelin' Man (RIP) on February 13, 2016, 06:47:10 pm
I bought (2) switches with activators from Mouser as Bill Willett had advised,  (1) NO and (1) NC for $16.95
including shipping.

Sorry for the confusion.

What is Mouser? Let us know how they work. I  am not sure how many I used but they are on almost every cabinet and closet door in my coach.  most lighting circuits have switched power as well so the doors can be opened without turning on the lights. 

These are low power switches (3 watts). Watch how much you are switching on.

I received my Mouser order yesterday and here are the results;
Mouser Part #: 540-MP201802 checks out as a NC switch
Mouser Part #: 540-MP201801 checks out as a NO switch

Mouser's got it right!
Thanks again Bill.
