Hi,

I am new to this forum and very green as far as electronics are concerned.

I need help or suggestions with respect to a new project. I have a basic underwater housing for my video camera. It has no capability to switch the cam on or off, and I would like to add this without drilling holes in the casing of the housing. I have approx 45mm of space at the back of the housing and my plan is to us a reed switch and a magnet connected to a solenoid to press the on/off button of the video cam inside the housing.

I need a small solenoid around 6 - 9v strong enough to press the button, and a reed switch that I can rig a magnet on the outside of the casing to activate it. The housing is 1/4" thick.

The array of reed switches and solenoids available is bewildering, can anyone suggest items that would be suitable for my project.

Many thanks,

Guyon

 

How much force does it take to activate the button on the camera, and how far in does it need to be pressed?

 

It only needs a very light force about 4oz pressure and it only moves in about 2 to 3 mil.
