Reed Switch Toggle On - Off:

Following on from this Blog Post on Reed Switches.

Using the 'building block' method, married up the switch debounce circuit with a CD4013BE 'D' Type Flip-Flop IC, added a reinforced- amplified output, for operation with a single Reed Switch to Toggle On-Off, for example coach lighting.

Reed Switch could be hidden inside in the roof, using magnetic wand, to activate the Reed Switch to turn the lights On and Off.


Hall Sensor version of  CD4013B Toggle On -Off.

Variation on the idea using.......

3.3V to 12V version, set at 5V with the Recom switching regulator.

9V to 24V version, with the LM2596 DC-DC Adjustable Voltage Module.
