MRS' Are No Longer Unobtainium.

[John Robertson]

For those that don't peruse Pinside, just making a repro part announcement. M&M Creations began making repro MRS' in mid-2019 - but only announced on the Pinside RFM forum (they are handmade and didn't want to get overwhelmed with orders). We've been branching out more to other Pinside clubs that utilize the formerly unobtanium switch....the MRS stands for Magnetic Reed Switch - they are also found in SC, CV, NBAFB, NGG, SWEP1 and CC ...they went unobtanium half a dozen years ago or so - so my partner and I at M&M Creations decided to remake them. Our MRS is plug/play - it is lighter, thinner and more sensitive than the original MRS (which we've found is key when playfields are restored). MRS' are $25/switch - same as they were about 6 years ago when they went poof!
Further, we designed an MRS mod for CFTBL to be placed on the whirlpool to garner more revolutions instead of the Cherry switch getting whacked by the ball. If interested, simply gmail or PM via Pinside if you like...

That would be part number 20-10293. I used to have stock on them...

From your description it sounds like a reed switch with a pre-trip
magnet placed close enough to the switch that the eddy magnetic field
generated by the steel ball rolling past trips the reed switch.

More or less...

Nice to have a replacement!

You are correct John! They are handy for other switch applications (since they are plug/play for almost all WMS pins) we've found as well - versatile little guys for certain. The most interesting we've seen is when playfields are restored and the original MRS' aren't sensitive enough any longer due to the greater thickness - 1mm can be a make/break point for MRS'...

Are you still making them? I am trying to find a very reliable Star Rollover switch for a homebrew project. I sent you a message earlier and hope it makes bits way to you.

Hey John - we don't have a website. We tend to design reed switches for problem areas where there are design problems and poor ball detection. So the switches can be custom for certain situations with different ball sensitivity. We do have a some standard stuff for ramp bowls, like Creature, Diner, and the slot rollovers are fairly universal but we still have to look after mounting compatibility and sometimes interference from other pinball mechs like magnets, etc. We do show what some of our stuff looks like and what applications we have worked on this pinside post:
