What would be the top and bottom of the Z both lean slightly to the middle, so if you try to push the points back they will spring but it won't actually move the solenoid, to move the points manually you must move the little nub sticking out the top. Not savvy enough to insert a photo to this forum, so I sent a photo to the email you have listed under your reply. manage your account online and more!

Create New Wish List; Share with a friend: Description. -An Atlas Snap Relay Switch can be used to to activate a secondary event once the switch to the primary event is thrown. Just a quick question, I have just replaced 10 Atlas #6 custom-line turnouts and 10 Snap relays and together they are working fine through DPDT toggle switches. SNAP-RELAY: Double pole, double throw electrical switch driven by a solenoid. Since you've got one, I'd suggest checking the wiring. The lamps controlled by the snap relay shouldnot be anywhere in the circuit with the Snapper. A CD circuit should overcome that. If the wires to the Snap Relay are longer or of a smaller gauge then they could be introducing enough resistance to prevent them from throwing. <]>> No, but the snap relay would not solve the problem of switch motor burn out. When I go to connect it to the layout, the Snap Relay will not activate. They seem to work ok, I don't have them permanently wired because I found out that I needed a few snap relays for what I plan to do. So, I needed to figure out how to wire the frog and reverse the polarity using an Atlas snap relay. It measures 1.80 X 1.50 inches and is specifically designed for low current motors such as Atlas, Lifelike, Bachmann, etc., but it will operate high current machines such as the N.J.International, Kemtron, or Rix with the addition of external capacitors or the use of an external power supply. BTW, I only have a 4' x 8' layout, I live in an apartment so I'm limited. I am running a reverse loop and cannot get it to work correctly. 0000000728 00000 n With nothing else connected, try this. Various model railroad wiring diagrams including how to wire turntables, x-sections, dual CAB and trackside signals using ATLAS electronic components. He is also using incandesant bulb's fed off the output of the Snapper...should be either a separate supply for them or connect them to the input side of the snapper like Randy suggested.

I am using monetary toggle switches with rice grain lamps. Atlas 200 Snap Relay. This means that the #200 may turn easily while the switch motor may not. After much assistance on this forum, I committed to keeping what I have and purchasing Snap Relays and a Snapper as it was the most efficient use of $$. Saved by B Fowler. The three wires from the pushbuttons should go to both a switch machine and the snap relay control. (A solenoid is a cylindrical coil of insulated wire in which an iron core is made to move back and forth by a flow of electric current.) Any ideas would be helpful! The Snap Relay is part of the line of Atlas 150 electrical accessories and lighting. I only use My three MRC CM 20's for nothing but train control. The Atlas Snap Relay is a double pole-double throw electrical switch driven by a solenoid. For Ken's circuit you need a SPDT toggle, but not momentary as if the toggle was momentary the LED would not stay on. Using an Atlas Snap relay solves this problem as shown below The Atlas Snap Relay takes in positive power thru its common terminal, and then depending on the position of the switch it passes power thru either terminal A or B thru a current limiting resistor to the positive side 0000001611 00000 n Try a different one and see what happens? On the layout, longer wires are needed and that eats up some of the power. Hopefully that get you started with these interesting devices. Atlas Code 100 Railjoiners N/S HO Scale Nickel Silver Model Train Track #170. . I have an AR-1 and have tried many wiring combinations with no success. I took the lamps out of the circuit with the Snapper. I did this for a friend and we mounted the push buttons and LED's right on the track diagram on his control panel. 24 0 obj<>stream Pushbuttons are SPST throw switches and you need two to operate an atlas machine with one side of the two connected together, which makes them Single Pole Double Throw. Almost all My turnouts are Atlas/Shinohara with Atlas under-table machines and snap relay for frogs and control panel lights/some signal Led's, which have a separate 12vdc 4amp power supply to the relay. Feb 6, 2017 - This blog follows the inspiration, ideas, design, and construction of my HO scale 4x8 model railroad. It includes all electrical components, wire leads, indicator lights, switches, and resistors. You can comment below. %%EOF It would appear that a Snap Relay doesn't have the over-center mechanism that is on the Atlas swith motors. Read more. 0000000808 00000 n It takes an iron man to play with a toy iron horse. I ran two power wires off the Snap Relay Common (one to lamps and the other to turnouts and toggles). the output of the snapper should go to your pushbuttons. The atlas turnouts work smoothly when the Snapper is inserted but the Snap Realy does not work... ...My furstration is that it works on the test bench (toggle switch, turnout, snap relay, snapper and transformer all the same) but not on the layout. POWER REQUIREMENTS: The Snap Relay is powered by connecting the 3 end terminals in parallel with the switch machine. 0 I am using an older Tyco 895 Transformer, and my assumption is that it is not powerful enough (amp wise) for full function of the turnout and relay. This is a poor product if you want it to last more than 25 throws. "It works on the bench but not on the layout" is a common issue with twin-coils, but the solution is usually to get a CD circuit. Was: C $21.92. Modeling C&O transition era and steel industries There's Nothing Like Big Steam! Now to the next issue. Use it to control trackside signals or indicator lamps for turnouts.
