These nifty devices let you turn something on and off from a regular R/C channel. They're lighter, faster and more reliable than using an R/C servo to knock a microswitch. A switch block provides four threshold positions to set where the D-switch turns on, and an LED indicates the status of the comannd coming to the D-switch. Microprocessor controlled and digitally filtered, the D-switch also employs fault detection to safely switch off the load if the receiver signal is lost, making it a failsafe. The unit is powered entirely by the receiver, drawing only 13 ma. The switched load is optically isolated from the R/C circuit, allowing two completely separate gounds to run without coupling noise between them. (Note to those running 6 volts on their receivers: placing a small 1N4001 diode in series with the power lead to the RCE200 will drop the volt or so necessary to let the D-switch run happily on your system. Simply request the extra diode when you order!)
