Hi ppl, I need to buy 4 or 5 rotary switches for my light baybus(5 1/2 inch bay) so i can turn on/off 4 CC's and a el string invertor- i presume it needs to take 12v as i am goin to wire it up into the 12v red power line?---is this feasable?--and can you get them with an LED on/off too---hmmmmm saying that u would know if the cc was on or not lol! any RS or mappers codes would b great as i am fick--i have to order the knobs from RS so they match my fanbus..... any help would be greatly appreciated............ta in advance
I am not really sure what you are asking, it is early here. But remember that the 12v lead is the yellow wire, red is 5.
hehe well reminded-----doh1--it has been a hard days slog 2day i want to be able to mount 4 or 5 rotary switches on the front of a 5 1/2 inch bay to turn off/on my cc's and el string invertor--i was going to splice the rotary knob into the 12v line---and lead all the wires upto the lightbus(?!!) just wanted to know what part codes as an example i would need to buy--looked at their online stores and it just confused meh--- :0
PHP: FF76H Rotary SW3B In Stock £1.29 £1.098 £0.988 (5+) FF75S Rotary SW4B In Stock £1.29 £1.098 £0.988 (5+) FF74R Rotary SW6B In Stock £1.29 £1.098 £0.988 (5+) FF73Q Rotary SW12B In Stock £1.29 £1.098 £0.988 (5+) Maplins codes... Any of them will do all u need to do is cut the 12V wire (yellow one) and insert the switch in there
thx biggie---are they quite bulky or can u hide them ok behind the faceplate---i got to get sum ribbon cable and conn for my blue vfd that arrived this morning--so i will pick these up too-- thx guys!!!
u are a star m8--i presume i can lop a bit of the length of the shaft--and what is the diam too?----gotta order sum matchin knobs the same as my fanbus
take a bit off the end with ya dremel, there are no wires in there.... (mine still work anyway ) diameter is approx 6mm, there is just enuff room for the knob to go over the end of it
luverly job m8----mine are gunna look scweeet---/methinks a trip to mappers in kingston is well overdue thx for all your help biggeh
gunna resurrect this thread---I ordered the switches--the same ones u got Big-- questions i have are-- you got 2 way or 3 way ones--mappers ordered the 3 way ones for me-spose i can still us the 3 way ones?--- have they got the ability to turn an led on when u turn the switch on--ie i want a row of bluu leds to indicate which ones are on/off-can these switches handle that?- which pins did u solder too as there are like 15 on the bottom!lol--sa wthe centre ones -- but what about all the ones around the outside-- I can still buy the switches as they are sittin in mappers store cupboard:/--just wanted to b doubly sure tho' thx for ya help in advance(again!)
any1 help at all?---need t know how to put an LED in parallel to glow when the switch is in the on position---
should be able to wire them in series on the output line from the switch, so that when the switch completes the circuit (turned on), the LED glows As for the rotary switches.... you have three poles for each channel in the centre (that is the case on the switches I have) You have 3 poles and 4 ways which the switch can be.... so, if you are just turning on the one cathode with the switch... use A and 1 to connect to the 12V line and then your switch will go from off to on at the first click For more than one cathode off one switch, turned on at the same time, use B and 1 and if u want one to turn on when another one is off... use A and 2
cheers dude!--i take it an resistor is going to be needed for the led in parallell across the two lines?---as it will b the 12v line-
yep.... I almost forgot that bit! Well ok, I did forget about the voltage when considering the LED! In that case, u need to run the LED in parallel, so that the cathode doesnt suffer from the drop in voltage.... something like this should work.... Ph34r my l33t MS paint skillz!
yup--exactly what i had in mind---- how do i go about workin out the res value --it is just gunna b ya standard bright bloo led?--or can i use an approx val res?(guess at the value!)--any ideas any1?-ie what 0hmage lol!-- i have a multimeter but would like to do it the easy way
