This switch is a superior design that is affected by time and corrosion as compared to that famous early model 720 with defined roadbed that warps and never works right . The 720A is the same switch , same as above, but made with the better bakelite not styrene plastic. This switch when reworked properly will give you thousands of throws with autothrow systems and continue working reliabley. Some of these iterations are better than others, the difference being in the shutter filter material. The answer to the bulb problem is 2447 24 volt, cheap and effective, buy them by the boxfull (chinese) CASG
Timely video. Many of these switches I obtained needed a little TLC. Biggest problem I had was a voltage drop over the frog that put the reverse unit into neutral on my old Flyer engines.
Dave once again thank you for the detailed video. We'll I got my frontiersman a few weeks ago and now by total chance I found an 0-8-0 switcher #342 at a yard sale along with four switches, some uncoupler sections, a 944 crane car and a few intersections as well. All in a sad state but I'm going see how far I get. The switcher is running now so that's a step in the right direction at least 👍
That sounds good, congratulations on your acquisition, many variations of 342 were produced, most are pricey and rare, this is a good find especially if you restore/rebuilt it, 944 is also a good find.
Hi Dave i also use resistor to step down voltage on just the bulbs and not the voltage to the switch. It works great,and i can still use the regular green and red.
I have them switches and I try what you said about light bulb and the only other thing the track come form switch then go to cross are off be 1/2" or less but the switch light cove that other thing I have to have help to fix
Hi Gray, Thank you for watching, that is a good point. I too like the results using LEDs. I replaced several standard bulbs with LED in illuminated cars that I operate with the FlyerChief GP7 that run under full transformer power, something that would burn out standard bulbs and really cause them to heat up the interior of a plastic shell. Best! Dave

Hi Dave i use LED bulbs 18 volts and run really cool.

Marx are simple to repair.
