I use lever operated SPDT switches (http://cnc.en.alibaba.com/product/730052561-212162659/LXW5_Micro_Switch_Sensor.html) to control frog and track power. I mount them for throwbar control either above the benchwork, or below, using a homemade linkage. Trackpower is provided by the proper running rails to the switch, then a wire to the frog and a jumper to the insulated rail beyond the frog.
I find that mounting them above the benchwork and using the switch throwbar to operate them. Simple, expedient, and reliable, a bane to the high-tech and Dcc crowd, but it works for me. boB Nicholson __________________________________________________ --- In [email protected], Bob Anson <e2picasso@...> wrote: > > may be a little more expensive but I use Tam Valley frog juicers > > Bob Anson %~) > > > ________________________________ > From: Bill Lane <bill@...> > To: [email protected] > Sent: Monday, June 3, 2013 1:37 PM > Subject: {S-Scale List} powering frogs > >  > > I power my frogs using a DPDT toggle. 1 set of contacts reverse the turnout > motor.
