Some cameras have the possibility to be triggered by an elektric switch. Some camaras can be supplyed with an electric trigger by yourself. The switch must be switched parallel to the trigger inside of the camera.
A remoted controlled relay can trigger the camera now.

The advantage for KAP is that you mustn´t use any servo and mechanic. Sometimes the electronic circuit is smaller and lighter in weight as a servo. Allways the camera triggering is easyer if it has an electric trigger.


The circuit bord of the electronic switch01 is
only sized 25 x 38 mm.



If you move the stick, or turn the button at your transmitter, the relay of the elektronic switch turnes on or off. With the relay-switch (COM and NO) you can trigger the camera now. The triggerposition, that point of the stick on witch the relay has to switch, can be adjusted by the trimmer R2.

Whith the jumper X4 you can choose the movementdirektion. A LED shows that the relay is switched on. I use special bright LED´s for outdoor use.

At the contacts of the relay (COM und NO) you have to solder two wires to the triggerswitch of the camera.

The circuit bord of the electronic switch01 is only sized 25 x 38 mm and has to mountig drills at the edges.
