Basic Operation Functionality

THE PRESTO CARD converts the basic +/-12 V DC Reversing DPDT Toggle Switch operation of most Stall Switch Motors into simple, quick, manual push button or electronic digital pulse operation for each throw direction.  The digital logic and motor driver inside the card memorizes the last press or digital pulse, and always completes the throw, regardless of how short the button press duration, and then keeps the motor powered in the correct position, until a different direction is selected.


The New PRESTO tm Push Button Switch Motor Controller.  PRESTO card will operate the MOLE, the Tortoise and other suitable, low current 12v DC stall motor switch machines.
