[January 24, 2026] All MP Series Switch Motors are BACK IN STOCK and we have adjusted our prices to reflect tariffs, shipping and currency conversion!

With the introduction of the new MP8 we've had a lot of interest in MP motors and we've seen many orders where customers are "sampling." To encourage you to look at all your options with MP Motors, we're offing a Discounted Evaluation Kit with a few options:

• The basic kit consists of 1 (each) MP1, MP4, MP10, and the new MP8, mounting adapters for new and Tortoise by Circuitron (tm) replacement installation, and a new install mount for the MP10.
• Optionally you can add our "control adapter for stall motor controllers" which allows you to control an MP motor from any DCC Decoder that can drive a stall motor (You need to supply 12V power either from your layout's 12V bus or a 12V wall wart)

See the product pages for the respective products for more details.
