I'll certainly increase the accessory voltage later today and hope that resolves the problem; however, I understand it may not be the answer, given that test at 7Vac.
I've not been able to identify friction problems in the moving parts of the switch. I did try a small bit of grease with no success. The lantern is not the cause, my video and all my tests were without a lantern cover in place, while the LED light shines brightly. Also, I did not find the extra plastic nub that was the cause jamming in Sean's Train Channel problem "FasTrack Switch Stand Jamming the Switch" at YouTube.com/watch?v=O9s7wTvwO0 .
Thanks for your suggests guys!
FYI: l have to add that problems with 3 out of 4 of the old O22 switches were the final straw that convinced me to join my "FasTracked" grandkids.
So I've been buying used FasTrack and FT remote switches at one-half to one-third the cost of new since June. Of course I had to buy some odd little new pieces from my local hobby shop. Ultimately, if I only have one non-functioning out of 8 used switches, then l live with it and the spare parts. LOL
