Instructables

How would I solder a Soft Push button switch to an LED circuit board from a Solar yard light?


I'm currently working on a project similar to slchorne's "handheld solar power supply" instructable and have run into a little trouble. The device will use a circuit board/LED light from a solar yard light and an SPST Soft Push button switch (with some new wires of course) as a flashlight and I'm not sure how I would connect the switch with the circuit board and the battery pack so that it functions correctly. Would I solder both ends of the switch wires to the circuit board or would I solder one end of the circuit board and one end of the switch wires to the battery pack?

An on off switch can be anywhere in the circuit. It simple breaks the flow of power. You will need a return wire that does not have to be switched. Think of electricity like water moving through a series of hoses and you should be able to figure it out. The placement of the switch is usually for the operators convenience.

This leads me to yet another question: How would i connect a blocking diode to the solar cell to battery pack circuit? Which wire, positive or negative, would i put it and which direction would the little silver ring of the diode face?

In that case I think i'll go with the video i got the idea from and connect it up to the circuit board...Thanks for the tip!
