At M&M Creations, we first remade the previously unobtainium Williams MRS as found in: CC, CV, SWE1, SC, NGG, NBAFB & RFM - then we moved on to create custom MRS' for pins with bowls - who doesn't like watching the ball go 'round & 'round - CFTBL, Transporter, Diner & CC....but we wanted to broaden our horizons a bit with something a little more universal in it's application....so we would like to introduce a self-adhering MRS for plastic ramps/subways.....sorry, but sheet/wire metal ramps are a no to physics : (

The ramp MRS is plug & play - it simply sticks to any flat surface on a plastic ramp/subways (sides or bottom - kind of like NBAFB & CC does) and can come with bare wire leads for splicing (green to green, white to white) or if you know the length of wire needed to get back to the connector under the playfield - we are more than happy to connectorize it - Either way the ramp MRS is universal with all DE, SEGA and Williams switch matrix's....SYS11, WPC89, WPC95, PIN2K, Data East v3, the Sega Whitestar stuff.....the places you can use them are innumerable - I put some pics up so you can see what I'm talking about - there are a lot of applications to be found where sticky Cherry switches don't register, or hold up the ball or slow it down......and frankly, I'm sure some of you can even find other applications for it.

We thought it'd be good to having something a little more versatile - so here it is....see below - or more importantly - ask questions....pics are from CC, RFM, SC, CFTBL and of the MRS itself......remember, it's just pics - really for nothing more to get the brain going to kind of get the application - since there are so many ways to apply them.....

Quoted from P1nhead:

Nice. I just had my left ramp exit switch on RFM break (again). I think I'll be in for one of these.

Good deal....just send me a PM - let me know if you want it connectorized or just bare wires to splice.....you know the drill!

Quoted from Jjsmooth:

How much are the MRS?
Any discount for quantity?
Jerry

What the heck?!? I was literally just going to PM you....that's nuts....shoot me a PM - I saw your Taxi resto and we wanted to create an MRS for the Spinout - but that's one pin we don't have (BBB, CC, SC, Transporter, Spirit - sure, but no Taxi? : ) ) .....so we were looking for some measurements and a tester.....

Quoted from Gornkleschnitzer:

So am I correct in assuming that this switch essentially works like an eddy sensor? Ball rolls near it and it registers?
If so, this is the perfect thing to fix the one remaining annoyance on my homebrew.

Correct....MRS' were used in various Sega and WMS pins....SW:Trilogy & Space Jam and Cactus Can, SafeCrack, Cirqus Vol, NBA Fast, No Good Gof, Revenge From Mars and SW: Ep 1.....

As far as your homebrew - if your using the same diode switch matrix approach as WMS and DE/Sega pins - yes - plug/play.....green to green, white to white as they say!

Quoted from Gornkleschnitzer:

I think I have my switch matrix wired backwards, but a little experimenting and I think I can make it work.
Where do I sign up?

Just shoot me a PM!

#11 1 year ago

$30/piece....some have kindly expressed their feelings about the price - but when the original MRS' went extinct nearly 7 years ago - they were $25/pop...these are smaller, lighter and more sensitive.....hand built... not easy to make....or tune!

#13 1 year ago

Thanks DeeGor for your purchase - I'm working on it as we speak!

Quoted from Brijam:

I assume these would not work as trough switches? I’d love to see something that replaces trough microswitches (other than optos). My immediate need is for a Stern IMVE.

Yep, plastic subway ramps are the idea.....we haven't worked on them being used in Stern games however, that's one of the next steps...right now WMS & DE/SEGA pins...

Take a look around the CFTBL forum - you'll see pics and testimony.....it comes in black and green

The bodies are not flexible - they are rigid. So no bending.....there is a 3M adhesive already applied, correct. Several folks have used this version of the MRS to replace ramp switches....you can see a write up on the IJ forum and the WhoDunnit forum - to name a few. These are for flat surfaces, but can be custom fit to curved surfaces if needed. Let me know if I can answer any more questions!

These MRS work really well! Trustworthy seller.

Thanks man!! Glad to be of help!

Quoted from pinballplusMN:

I'm wondering if this can be used on eightball deluxe. Mainly as a substitute for the star rollover.

Likely not....playfields are fairly thick (~13mm) - the original MRS' used in the 90's era pins had pockets routed out on the playfield to allow about a 6-7mm thickness at that point....

Quoted from mwong168:

This would be great for The Shadow's left ramp, right side divert to wireform to right flipper which often doesn't register. I have tried installing a longer wire arm actuator which registers 70-80% of the time.

Well then mwong168 , today is your lucky day - head over to the Shadow forum....just PM me for purchase details...

Quoted from mystman12:

Any idea if this would work for the center ramp on Mousin' Around? It's pretty wide, but I'm missing the switch bracket so this might be a good solution. I just want to be sure it will register since the ball won't usually come through against the right side of the ramp which is where I'd probably put it.
[quoted image]

So the gap between the ball and the right side of the ramp (from the orientation of the pic) is - would you say <1/2"? Having an accurate measurement of the gap is key - that would determine the sensitivity. I assume you want to put it on the wall of the ramp - but could you put it underneath the ramp and centered?

Quoted from Markharris2000:

MRS works on proximity, and for the same reason it won't work under a playfield, there is simply too much distance between the ball anf the MRS so the magnetic field doesn't get disrupted enough.

Just to clarify, Markharris2000 - MRS' were used by WMS under playfields (and some ramps)...

No problem having it on any side of the ramp - let alone having it further down the ramp - it really doesn't matter as long as it is somewhere on the ramp...my fear underneath is the distance between the playfield and the bottom of the ramp....not having a Mousin to look at...putting an MRS down further where the ramp narrows would be your best best...you simply need longer wires to the connector. It can be adhered to anywhere flat on that ramp, accept an arc - for that we'd have to measure the radius...and make it custom.

#40 1 year ago

The originals were pretty limited in sensitivity (at best 6mm) ....and yes sat in routed pockets....however ,some were put under inserts....however our MRS' are more sensitive - not a full playfield thick sensitive....but a good 33% more than the originals....

Quoted from mystman12:

Got mine a few days ago, and it's been working really well! I ended up sticking it near the end of the ramp, as that was the only spot where it would consistently register. Up near the entrance, it was so wide that the ball would often bounce around and not hug the side of the ramp, and as a result wouldn't get close enough to the switch.
Glad I can finally get the full Mousin' Around experience!

That thing looks great!! So glad to help ya.....thanks for your patronage!

Quoted from Maurice:

Can this mrs switch replace a inductive switch on an Alien from Heighway Pinball? I want to replace the two inductive switches in the upper inner loop, which are located in the playfield. There are small round holes that give acces to the playfield surface. So a small round inductive version would be perfect.
However the inductive switch is a plug and play switch connected to a large board. Maybe the wiring is different or not possible?

It is possible - but it depends first as to whether it's on a switch matrix of some sort....the MRS simply provides an closure upon ferrous detection (i.e. the ball).....if the Alien pin switch does the same - then it could work....do have pics or possible schems? Any further info could help since these are about a scarce as they get - I certainly don't know of any I can go look at...

Not on Monday - but shortly after, we have been talking about running a sale - so yes....just trying to catch up on orders for our newest switch (it's for JJP POTC) at the moment...Is that Taxi needing a spinout MRS? : )

Quoted from Bellagio:

Good memory! Yes I’d like to get one, so holler at me when you have the sale. Thanks!

Do me a favor, I use the PM here as a queue - shoot me a PM - that way I'll have you in line...

Quoted from Maurice:

2x3 legs go into a socket on a large pcb below The playfield.

Any sort of schems? I assume one socket is power- the other is the switching portion....curious, does this switch not work well? These inductive proximity sensors typically work well......
