Centrifugal Switches

[Marky_Mark]

Has anyone ever had trouble with the cent switches not coming back down all the way when the cent mechanism has stopped. And then when the motor restarts it hums and the reset pops. Upon looking thru the side of the motor on top you can see the switch has not returned in the down position. Pushing it with a screwdriver returns it where its suppose to. Ok, so how do I correct this troublesome problem. Or have you found a solution without a big expense.

Sorry, Im refering to the combo National motors. 50hz and 60hz.

Re: Centrifugal Switches

Good ol Matsu****a Electric

the prob is the switch itself has a grove in it......file out the groove on the back side of the switch and it will flip easier. dont blame the mechanism.

some mickey mouse alternatives...spot weld the mechanism so it cant flop up and down the 1/16 of an inch between the fat part and the cotter pin.

use washers under the switch to help te switch get down.

the proper way i think is to get a solid state start switch....ya gota do a little rewiring but no probs after

Re: Centrifugal Switches

I have tried the washer trick, didnt help. But do you have a part number for the solid state switches. I dont see any in the parts book. As for the groove, didnt notice one in there so I will have to look. And yes, your right, they are the Matsushi motors.

Re: Centrifugal Switches

I don't think that AMF sells solid state motor switches. You'll have to get them from another distributor. Although there are many to choose from, some probably more reliable, I like the switches from Quality because they are repairable (for <10% the cost of a new one) The # is A-110-663-500. They also have one for the backend motors, # A-110-663-510 but the ones for the combos will work too if you open the case to allow the heat to escape.
On our original National motors, we put a panel mount Molex receptacle in the opening of the top cover of the motor, right next to the plug cover &amp; put its mating plug on the switch. (The after market motors need a pigtail) The instructions say to mount the switch to the side of the motor with the Velcro supplied with the switch but that can cause vibration &amp; heat related failure. We mount the switches to the wireway. We also hang spare switches on the curtain wall. That way we can change the switch in just a few seconds, instead of taking 5 min. to change the motor.

Re: Centrifugal Switches

Actually, AMF sells the best Solid State Switches for Nationals, (Of course just my opinion). I've burned up a ton of Quality’s vs. one AMF.

The disadvantage to Quality’s is you have to do some minor rewiring to get the sweep to reverse automatically when interfacing with your scoring system.

AMF part # 610-309-042 costs $47.25 and worth every penny. A big advantage is that the AMF SSSS is adjustable (which comes in handy for old weak windings that still have a few years left in em.) Another advantage is: that it will work on Back End motors as well.

Question: By removing an internal OEM part and replacing it with a better external part, is that mickey mousing?

by definition....yes....the new SSSS is in place of

so if you use the SSSS in addition to the mechanical switch, its not

Re: Centrifugal Switches

Atleast someone is getting my point!!

Re: Centrifugal Switches

LOL...Another SSSS that has proven itself was Murrey's, but my distributor told me they don't make those ones anymore.

Mickey Mouse...(It sure looks like it)...or not!! External SSSS is the way to go!!

Re: Centrifugal Switches

Tech,
The Murrey &amp; Quality switches are identical. We started getting them from Quality when Murrey stopped selling them.

Re: Centrifugal Switches

WE DO STOCK SS SWITCHES! They are virtually the same as QB except we like ours better(duh) and you'll find the pricing better.We currently have 150 for combos and 60 for backends in stock. Hope this helps. Bill

Re: Centrifugal Switches

I thought that my distributor told me Quality bought them out but I didn't want to post it because of the uncertainty. I have disassembled all of em to see the difference in specs and design. Let me tell you its no picnic trying to bust out all that epoxy at the same time trying to preserve the #’s on the SCR’s and misc parts. But it can be done!

The Murrey’s we still have in service are NOT anything like the crap Quality's puts out!

Just my 2 cents and nothing against Quality.
Quality puts out very excellent products except their SSSS.

I stand corrected...(after talking to one of my mechs)...K&amp;B Electronics...I think I "heard" Murrey was distributing em...Are the ones still in service after many many years!

Re: Centrifugal Switches

Ive heard from a source that there is a high breakdown rate on the Quality SS switches. If this is true then which switch should I go to. The mechanical switches Ive been getting are from vantage, part # v785-502-190. We have had nothing but problems with these. Some work and some dont. Ok, any other solutions.

Re: Centrifugal Switches

I have been looking for KB Electronics 3 wire switches as they came on my BEnds, I did see a newer similar switch from Bowl tuff I think, at least the paper on it was new, lets find some.
