Here is a image adjusted (I've slightly boosted the red in the image) close-up: Mind, on my iPad, the red wire still looks black

Hi, panic over :mrgreen: Last night, I was going to put a link up to a picture that I posted earlier in the thread. But when I looked at it on a iPad I could only see three wires :shock: , and this does not tie in with the schematic that I posted :( However, after physically checking the wiring of t...

The company where I work requires 24 hour cover, so I have to do nights every cycle.

Actually, comparing the schematic and the pictures I have posted, there is an inconsistency . So can you hang fire please.

I'm at work right now. When I finish and get home I want to double check.

Mark, Can you confirm the ouput connections of F2 please? Red connection to DIN Plug 3 Black connection to DIN Plug 4 Black connection to R2 of LED Black connection to black output of strip board - This is the connection I can't see in the photos. Thanks. Yes, what you have listed is correct. On th...

Connect a temporary DC supply to the input terminals. I used a DC power supply set to 8V, but a 9V battery would be fine. If using a PP3 [NEDA 1604, IEC 6F22, MN1604, 6LR61], best use a brand new one. Connect a digital multimeter to the output terminals. Now locate the preset (variable resistor) on ...

Err... Where have you guys been?

As these are getting quite rare it's unusual to see them for this sort of price. http://www.ebay.co.uk/itm/HM6116L-120-Pack-of-5-/39101094579...

Ahh, yes, the plastic body would also be used with DPDT (double pole, double throw) and DPCO (double pole, change-over) type switches which will use six terminals.

I can't make out the wires! In my photos, they are very thin silver coloured wires that come out of the black plastic body of the switch and connect to the terminal very close to the black plastic of the body. Yes, very difficult to see. Your switch may not be the same. I've magnified the PDF and n...
