Starter Switch Problem
Has anyone experienced problems with the new foot operated starter switches currently available from suppliers?
Mine shorted out and would not disconnect.

Re: Starter Switch Problem
No troubles with the $32.95 style, USA mfg., have used these all the time.
No experience with the $14.95 style, too inexpensive to work well, IMO.

Re: Starter Switch Problem
With a new replacement I had to remove, it would appear that the heat generated in its use led to the bridging contact loosing whatever 'spring' it had, so that it would no longer disengage. I always use an original, rebuilt withe new insulating washers and cleaned up contacts.

Re: Starter Switch Problem
As Dan alluded to above - there's a cheap, imported POS available, who knows why - I won't carry them in stock and then there's the gold old Made in USA switch - I sold & installed dozens without any problems. Are you stating that you had the "better" one of the two go North on you, Allan ?

Re: Starter Switch Problem
Friend had gotten a second switch after his first failed ($32.95 style, USA mfg.). Gave to me to investigate. The problem is that a long plunger tube acts as a pry bar and bends the metal base IF not depressed straight down. So if it pushed for ward it will cause a connection failure. Review the pictures and decide. Solution for the weak mounting at the plunger base may be solved with a spot weld - if it can take the heat

Re: Starter Switch Problem
No Steve, it was a new, unbranded switch of dubious quality. While I can still find originals to rebuild, I stay away from any modern replacements, the best one requiring work on the bracket mount to get the plunger to fit the hole in the floorboards.

Nice photos and details. Might be wise to send your photos to Steve Lang and see if there is some type of issue with a production lot of the higher quality repro switches. The bend of the metal around the footswitch pedestal is interesting.
Have these switches on all of my T's and never issues like you are showing. About the only thing I take care is installing the extension sleeve. Spread the slots in the sleeve gently with a blunt screwdriver tip, so the sleeve glides on without any heavy hammering.
And make sure the switch plate is firm on the frame rail to keep the switch pedestal from being off-center. The load on that footswitch is only with slight heel pressure, as for me, the T's start right up fast with good tuning, don't have to engage the switch but just a few seconds.

Re: Starter Switch Problem
In 2001 when I first started purchasing items on eBay, One of the first items I bought was a very reliable original Model T floor starter button for my 1926 Coupe. It has never given me any trouble like I used to experience with the modern starter buttons which used to always arc and ground out. I have never had any need to go into it to service it, so I don’t know how it is constructed to make it so reliable, but I highly recommend buying an original if you can find one. Jim Patrick

Re: Starter Switch Problem
The way you have the switch protruding through the hole in floor board should prevent the failure of the plunger at the base. Only a downward force can be applied. Its the exposed height of the plunger & hole size in the floor allowing for to much forward movement that leverage will cause a failure. Which could also be caused by minimal gap between floor and mounting flange. I'm still concerned with the switch getting wet - same concern with the design of the original switch but not as much - it could drainDanTreace wrote: ↑Wed Jan 06, 2021 9:11 pmFrank

Where did it short out? externally across the exposed posts or internally? Did you take it apart - pictures?

Re: Starter Switch Problem
Mine was the cheap version. Instead of a bar to connect the two electrodes there were brass discs.
I was running my engine for the second time since rebuild and had been having to crank excessively, probably due to weak coils. New (rebuilt) coils haven’t arrived yet.
I dug out the original starter switch and after some clean up and rubber washer replacement it is working fine so far.
I will be on the lookout for more originals as I have three more T projects after this one.

Re: Starter Switch Problem
Normally, finding good original footswitches is a hit and miss for me.
The insulated washers are a paper type, and can be frayed and always need to be substituted with some other method. The contact band strip assembly most times are feathered worn on the ends, and lack good spring action.
The button contacts are normally easy to bring back to shape by filing flat and smooth.

Re: Starter Switch Problem
The earliest original Ford switches were held together with two screws much like the good USA repro (I believe they're a Ford tractor replacement) - those are harder to find but much easier to "service" unlike the 4 tab type as shown above.

Re: Starter Switch Problem
Steve, that's correct.
Or this way works, went to Tractor Supply and bought a 'universal' footswitch, probably for tractors or something. It has a rectangular base, so cut a matching hole in the Ford mounting plate for clearance and bolted on the new universal footswitch, still working good

Re: Starter Switch Problem
Just bought a new starter switch from a reputable supplier. It was junk from the get-go. Started the car a couple times and then the top popped off and the starter started running continuously. Had to take the battery cable off the starter. I did the same thing by altering the new bracket to fit a tractor starter switch. Maybe better results but if anything else easier to source.

Re: Starter Switch Problem

Re: Starter Switch Problem
What's the smaller "black" wire on the starter cable post going ? Battery cable to starter switch should and does have the main (yellow) switch feed wire - opposite post on switch goes to starter.

Re: Starter Switch Problem
Welded contacts is a common design problem with high-tension switches.
That's why they have strong springs.

Re: Starter Switch Problem
Sorry guys, the yellow wire that comes from the starter loom sleeve is connected to the upper or inner connection point which goes directly to the battery. The black wire is the tail lamp wire that is part of the loom. Left hand connection (closest to the frame rail) is the starter loom with sleeve; right hand connection goes to positive battery terminal.

Re: Starter Switch Problem
That's the correct way, Daniel. Appears to be an original switch - most likely the insulators both internal & external causing issues. Those type with the "bend over tabs" don't let you get away with multiple openings so you might bend them up easy & just enough to disassemble for inspection then anneal the tabs prior to bending them back over.

Re: Starter Switch Problem
I have an original with the bent over tabs, three of which were broken off. I rebuilt the insulation around the terminals, cleaned up the contacts and bridge on the plunger, and clamped it together. I light touch with a mig welder now holds it together where the three broken tabs were. rescuing good original is way better than the junk replacements.
Hope this helps.

Re: Starter Switch Problem
Some of my cars don't have electric starters but the ones that do I add a 6 volt solenoid. New or old I only use the foot switch to provide the low amp voltage to the solenoid, Mount the solenoid inside the frame and it is not particularly visible and only you will know as everything will operate as original. Plus, you will get better voltage to starter. Best to find an auto parts that can make cables for you. Don't use small available 12 volt cables. Unless you have gone 12 volt. With good large cables 12 volt not normally necessary.

Re: Starter Switch Problem
Bought a new switch for mine, and it started smoking after a couple starts. Pried back the tabs with a screw driver and found that the thin contacts arcked. just finished rebuilding an original.
