Inexpensive wireless remote controller for model railroads
This is an inexpensive controller that is used to trip a 12vdc circuit. It is used as part of an emergency stop circuit for my model railroad. The controller uses a FOB to activate the control circuit that is housed in a small power distribution box. Activating the button on the FOB trips the emergency stop circuit (not shown). The controller is used in momentary contact mode. The wireless controller shown was purchased on EBAY for $4.41 with free shipping.
Note: The distribution box also includes a fuse and LED power indicator. This same wireless controller module could also be used to switch power to an operating accessory or lighting. The module is powered from 12VDC.
