IANAEE. For an on-board application you can create a simple switch with a transistor. https://www.electronics-tutorials.ws/transistor/tran_4.html
To make something wireless you'll probably want to go with a microcontroller or Raspberry Pi and hook up GPIO pins to the motor controls. A transistor wouldn't be needed in that case as the microcontroller can hold the pin high or low depending on what state you want.
