Stall Motor Switch Machine Circuits

Stall Motor Switch Machine Circuits

Multiple Location Control of Stall Motor Switch Machines


Alternate Location Control of Stall Motor Switch Machines


Full And Half wave DC power supplies and other control options for Stall-Motor switch machines.

Very Simple SPDT of Stall Motor Switch Machines

The next schematic shows three methods of controlling Stall Motor Switch Machines with an SPDT toggle switch and two resistors. This method wastes most of the current.

Push Button Control of Stall Motor Switch Machines

The next schematic shows three methods of controlling Stall Motor Switch Machines with momentary contact push button switches.

These circuits might be of use if slow motion type switch motors were to be installed on a layout that already had push buttons mounted on the control panels. This would then allow a transistion to the new switch machines with out having to change the control panel's buttons.

In circuits 1 and 2 the buttons must be held closed until the turnout throw arm of the switch machine has stopped moving.

Circuit 3 will keep power supplied to the motor for a few seconds after the push button has been released, allowing the turnout to finish its throw.




Please Read Before Using These Circuit Ideas

The explanations for the circuits on these pages cannot hope to cover every situation on every layout. For this reason be prepared to do some experimenting to get the results you want. This is especially true of circuits such as the "Across Track Infrared Detection" circuits and any other circuit that relies on other than direct electronic inputs, such as switches.

If you use any of these circuit ideas, ask your parts supplier for a copy of the manufacturers data sheets for any components that you have not used before. These sheets contain a wealth of data and circuit design information that no electronic or print article could approach and will save time and perhaps damage to the components themselves. These data sheets can often be found on the web site of the device manufacturers.

Although the circuits are functional the pages are not meant to be full descriptions of each circuit but rather as guides for adapting them for use by others. If you have any questions or comments please send them to the email address on the Circuit Index page.
