Motor switches for model railway

• Motorized switches, quiet and slow motion
• Small size
• Included motor with planetary transmission
• Direct replace of electromagnetic motor or motoric switches
• Possibility to adjust the stroke degrees
• Integrated switching contacts
• Easy instalation
• Easy to set the basic position of the needle

The switches are used for the electrical control of two-position mechanisms in models, typically switches or mechanical signals and railcrossings.

The stroke is adjusted in several steps by the position of the pin in the carrier. The sliding mechanism ensures a smooth approach to the end position and its arrest.

The power supply is direct current and alternating current in the range of 9–16 V, consumption approx. 150 mA during operation. The mechanism is equipped with limit switches position, the control power supply can be connected permanently, after reaching the appropriate position, the current consumption and movement are automatically disconnected.




MP1 Basic model railway switch

• Motor switch with silent and slow motion
• Miniature scantlings 28x40mm (w x l)
• Inbuilt motor with planetary transmission
• Direct replace of electromagnetic motor switch with three-core connection

The motor switch is used for electric actuation of the two–position mechanisms in models, such as turnout points or mechanical signals and barriers.

The stroke can be set in three steps 3 mm, 6 mm, 9 mm – see the illustration. The cam mechanism provide slow end position stop and lock.

Electrical connection is the same as old–style electromagnetic switch and MP1 can directly replace them without changes in wiring of model layout scheme.

MP1 is equipped with one SPDT contact for auxiliary purposes, like frog polarisation, with capacity 1A.

Connect to the COM+ terminal with DC powersupply. The F1 contact will close once the movement ends up at the Position 1 (or the Position 2 in case of the F2 contact respectively)

MP4 Advanced model railway switch

• Cheaper replacement for MP5
• Miniature size
• Universal connection of electromagnetic or motoric switch
• Setting of 4 stroke ranges 3, 6, 9 a 12 mm
• Two auxiliary switching contacts
• Detachable connector for easier installation

Both DC and AC power supplies are available, with consumption aprox 150 mA during motion. The mechanism has a position end limit switch, i. e. the control voltage can be applied permanently, to be disconnected automatically once a respective position is reached and the motion stops.

Electrical connection is the same as old–style electromagnetic switch.

The stroke can be set in three steps 3 mm, 6 mm, 9 mm and 12mm – see the illustration. The cam mechanism provide slow end position stop and lock.

MP5 is equipped with two SPDT contacts (1A) for auxiliary purposes. Easy installation with removable screwless connector.

MP5 Advanced model railway switch

• Miniature size 30×42 mm (v×l)
• Universal connection of electromagnetic or motoric switch
• Setting of 4 stroke ranges 3, 6, 9 a 12 mm

MP10 Versatile motor switch

• Size compatible with the Tortoise Slow Machine™
• Slow movement, higher feed force
• Two- and three-wire control
• Setting of 4 stroke ranges - 3.5, 6, 9.5 a 12.5 mm
• Two auxiliary switching contacts
• Detachable connector for easier installation.

The MP10 combines the features of the basic MP1 toghether with MP5 while maintaining a low price. It is designed as a compatible replacement for the Tortoise (USA) motor switch, with same mounting dimensions.

Modifed mechanical transmission increases power and slows down the speed of movement, the MP10 is suitable for larger ganges, like 0.

Stroke adjustable in the range of 3.5 – 6- 9.5-12.5mm.

Two independent switching contacts with a capacity of 1A.

Two-wire connection mode – position movement controled by the polarity of the power supply (like Tortoise), after reaching the end position, the motor turns off. Alternative three-wire connection mode - function same as MP1 or electromagnetic switches.

How to change the distance of travel


1 Unscrew 3 screws on the housing bottom.


2 Remove the slider assembly.


3 Set the pin to a desired position


4 Reassemble the set and fit the housing. Carefully retighten screws. The switches must get in contact with cams, but beware                        of plastic parts while retightening. Excessive effort might cause damage to them; try with the screw first.

Setting the length of needle


1 Unscrew screw on the check gate of motor switch


2 Set the required length of needle and screw up screw

Setting the needle longitudinal position


1 Unscrew 2 external screws on the check gate of motor switch


2 Set the required position of check gate with respect to the end position of switch
