Bulgin AC power switch

merlin el mago · 12th September 2011, 02:23 PM

Hi have a couple of Bulgin AC power switch:

BULGIN|MP0045/1E2BL012|SWITCH, FLUSH LATCHING, BLUE ILLUM | Farnell Republika Slovenija

I measured the switch:

bicolour LED
Forward voltage Vf D1=3.80V D2=3.78V
Test current If D1=1.31mA D2 3.78V
D1 measured +- as marked in the switch
D2 measured +- inverted as marked in the switch

How have I to connect it?

Many thanks marce, still I don't know how connect the AC voltage? I can't understand NC1, NC2? only switch (have or not have continuity depending switch position) NO1 and C1 or NO2 and C2 so can switch on/off two devices, I read that some LEDs needs a series resistor, guys really I'm lost, please help will be welcome.

I have these switches and I don't think you connect AC direct to it. It is a push button type not on/off type

I use this :The ε24 Power Switch Driver Circuit

Thank you necplusultra, I believe my switches aren't the same like AMB uses.

connect positive mains into c1 output from NO1
connect neutral mains into c2 output from NO2
the led !!!! cant remember whether the resistor etc is built in, sorry.
