Good morning,
Could someone advise on the name/brand/model number and possibly where to purchase an SPDT switch for reversing the directions of the Marklin 1071 electric motor.
Thanks for your assistance.

Would the Marklin HO 1323 switch work with the Marklin 1071 electric motor?

Moved topic into the 'Construction Kits' forum. You asked a similar question previously - https://www.marklin-user...arklin-1071-ElectromotorAre you still using an AC transformer to power the motor? Nice to see that Christian at Modellbahn-Center Recklinghausen has a 1323 switch available for purchase - https://modellbahn-cente...aukasten-motor-1072.htmlThe 1071 is an AC motor, so you should be able use the reverse function of the transformer to reverse the motor. I don't know if the 1072 motor is AC or DC powered, but if its is AC powered then the 1323 switch might work with your 1071 motor. Try it and then report the results! As Cookee asked in that previous thread "What you are using sounds perfect for the job, why do you feel you might [need] something else?"

If the 1071 motor is modified as described in this forum a few days ago you could use the
1323 switch as the SPDT (and off position) switch.
Both the 1071 and 1072 are ‘universal’ motors which work on either AC or DC current, they have wound field magnets, not permanent magnets like DC only motors have. Because they each have two field windings - one for clockwise and one for anti(counter)clockwise direction is selected by which field the current passes through. They are both ‘series wound’ motors which means the current passes through the armature via the carbon brushes and then through the appropriate field winding. So as current increases with load through the armature the current also increases through the field coil strengthening the magnetic field. Some other motors might be parallel wound such as full size older electric trains.
The analogue Märklin controllers are ideal for these although I use LGB controllers which have
higher voltage and current possibilities.
Later Märklin Metall motors had permanent magnets for the field, they could still be used with AC because they included diodes to convert the AC to DC.

Märklin used to sell electrical experimentation kits under the name ‘Elex’. The largest of the three included parts to make a two way telephone but all, I think, included the parts to make an electric motor that could be used with construction kits. The beauty of the motor is you can wire it as a universal series or parallel wound motor or use magnets to make it DC only. You decide on the best configuration, it certainly helps understanding of electrics and magnetism. Meccano had its electrical kits too.
Sadly most were brought up on L**o which though entertaining doesn’t have the educational elements of Meccano or Märklin.
