It only uses one IC and seven other components for a single switch and you can build two or three to run from one output channel of your receiver, which will allow you to switch the navigation lights, cabin lights and deck flood lights of your vessel in sequence.
The circuit is a so-called “Radio Controlled Electronic Switch”. The schematic diagram in Fig 1 shows the setup for switching general accessories such as motors, relays, navigation lights, landing gear, sound systems, glow plug driver, bomb release, parachute, search lights, gyros, and so on.
Please note that this system will not work with PCM.
Datashwet this monostable times out its inverted ‘Q signal goes high and clocks the output stage of the Flip-Flop, datashedt is used as a normal type ‘D, to sample the input pulse. If the duration of the input pulse is longer datsheet the preset monostable pulse, then a logic high level will be clocked to the output of the D type. A shorter input pulse will cause a logic low to be clocked to the output. In short, both halves of the IC perform two different logic functions.
The k potentiometer sets the trigger point at which the circuit will switch on. If you intend to make a printed board in order to construct your switch, you will need some presensitised PCB material and Caustic Soda for developing. Then you will need to etch the copper to form the tracks using Ferric Chloride. A board layout indicating where to cut the copper tracks is shown in Fig 5 scale approx.
Page 2 of 8. For the resistors and capacitor bend the leads to suit the strip board hole spacing. A picture of a finished assembly can be seen in Fig 9. Now add all the wire links green lines shown in Fig 7. This may be vatasheet using some very thin Tin Copper wire. Insulate the link wires across the IC pins from the copper tracks that they cross by placing some insulating tape or masking tape over the tracks prior to fitting the links Page 3 of 2m2700.
Fig 7 Wire Links added Now you have added the wire links you are almost ready to test the device. But, first you will need to add an input cable that can plug it into your receiver and some form of output indicator in order to verify that the unit is switching correctly. Connect the servo lead to one of the receiver outputs. Adjust the potentiometer to somewhere in the middle and set the transmitter control to the point where you wish the Switch to turn ON.
Now adjust the potentiometer on the switch to the point the where the LED is illuminated. If it does, your unit is functioning correctly and you can play with whatever other setup you have in mind. Fig 9 A competed switch assembly Should you wish to switch an item which runs from a higher voltage, first ensure that the negative of the higher voltage is common to the negative of the Receiver supply.
Then connect the item to be switched between the positive of the higher voltage dtasheet the Switch output. Should you wish to switch a number of voltages or connections at the same time then use the electronic switch to drive a relay, then utilise the relay contacts to do your switching, an example of such a system is shown as in part two of this article.
Page 5 of 8. A printed board was created to accommodate the relay and wire connection points. This layout is shown in Fig 11 and the printed board master is shown in Fig It will be noted also that this circuit uses a 2N switching transistor on the output, as the relay does not require such a high switching current.
All the other functions are the same as for the non-relay circuit shown in Fig 1.

A picture of the completed switch is shown in Fig 13 and a list of materials for the relay version is given in appendix B. Fig 13 Completed Electronic Switch with Relay Output I have not provided a Strip board layout for this circuit, but if anyone requires one I will be happy to provide some assistance in order to create the necessary layout.
This now concludes the article on electronic switches. I trust that the information has been clear, informative, not too difficult to understand and will be of some use. Should you wish any further information please do not hesitate to contact me at one of the monthly Club meetings, I attend most of them.
