MINIATURE, HIGH CURRENT SWITCHING,
INDUSTRIAL QUALITY, SDPT AND DPDT RELAYS


       RDP12                       RSP12

FOR EASY SWITCHED LIVE FROGS, DCC SHORT PREVENTION
AND MANY OTHER TRACK CIRCUITS

We are happy to explain how to use these for switching live frogs
and many other operations.  They are suitable for DC or higher current DCC use.
Please see our new Relay and Switch Wiring Information/Tutorial page for more details.
This can be extremely helpful if you are operating these switches manually,
or do not have sufficent extra contacts on your Switch Machine
(e.g. basic stall motor machines such as "Switch-Masters")

One or two RSP12's can automatically switch a live frog,
or set up DCC dead sections,  to prevent common DCC
short-circuit shut-downs, e.g. when a loco runs into a wrongly set switch.

An RDP12 is a more compact way of  having two RSP12's operating together in one package.
It can switch both the frog and dead zones for a switch simultaneously,
or automatically operate more complex situations such as reversing loops

INDUSTRIAL QUALITY  SUB-MINIATURE  "PUSH BUTTONS"

FOR "HIDE BETWEEN THE TIES" and other
HIDDEN OR "DISGUISED" MOUNTING APPLICATIONS


        The PSW1 Subminiature Push Button Switch - Click each picture to see closer views 

THESE ARE SOME OF THE SMALLEST PUSH BUTTON SWITCHES AVAILABLE
AND WILL ACTUALLY FIT BETWEEN THE TIES OF MOST HO TURNOUTS. 
They can be virtually buried in the ballast, or disguised as trackside boxes, or mounted on walls or poles as other railroad control paraphernalia

APPLICATIONS  INCLUDE "HIDDEN" TURNOUT CONTROLS, "HIDDEN" UNCOUPLER CONTROLS AND OTHER SCENIC APPLICATION WHERE LOCAL, BUT "INVISIBLE" SWITCH LOCATION IS DESIRABLE.

These switches are suitable for medium current (<100 mA) operation at 12v.  They are suitable for intermittent direct control of low current "stall" type switch machines and electronic circuit inputs, as well as our relays above. Use with a series current limiting resistor is strongly  recommended. We are happy to explain how to use these in conjunction with our relays for switching higher current circuits, including live frogs and many other operations. 

Part #,           Description                                                       Price

PSW1-2   Normally open, 100mA, Single contact                   $2.95
                 Sub-miniature push button. - Two pack

INDUSTRIAL QUALITY,  MICRO-MINIATURE 
"MOVEMENT" LIMIT DETECTION SWITCH

USEFUL FOR DETECTING THE POSITION OF MANUALLY OPERATED TURNOUTS
USING HIDDEN OR "DISGUISED" MOUNTING APPLICATIONS, ROTARY CAM POSTIONS, ETC.

 
        The NSW1 Micro-miniature Limit detection Switch - Click each picture to see closer views 

THIS IS ONE OF THE  SMALLEST LIMIT SWITCHES AVAILABLE. With only a moderate effort this can be fitted into the extended ties of a switch and used to detect the switch thrown position, or the setting of a manual switch  throw.
It can be virtually buried in the ballast, or disguised as a prototype switch motor or dectector.

These limit switches are suitable for medium current (<100 mA) operation at 12v.  They require a force of approximately 8 oz. to activate, and will only allow for movement of up to  0.010".  Your model must be able to repeatedly and reliably exert this much force without damaging itself.  They are suitable for intermittent direct control of low current electronic circuit inputs, as well as our relays above. Surface mount solder ear connections - recommended for solder mounting across two adjacent PC ties with wiring taken from the other end of the ties.  We are happy to explain how to use these in conjunction with our relays for switching higher current circuits, including live frogs and many other operations. 

Part #,           Description                                                       Price

NSW1-1   Normally open, 100mA, Single contact                   $1.99
                 Mico-miniature Limit Switch.
