Hello All,
I got the C5503ALNAK switch and I was attempting to connect it to my circuit but its datasheet is one of the worst I have ever seen. There is only this diagram. Does anyone know what that circle with the 2 lines and a dot represents, and do you know which terminal is positive and which is negative? How should I connect this thing...

It's normally used as a lighted mains AC switch if there is a neutral specification.

When switched on, a switch closed contact is connected the bulb (likely neon per the dot in the lamp symbol) on the other terminal and the load power terminal.

Without the switched neutral the bulb is always connected.

Thank you! I was able to connect it to the circuit and turn the current on and off my circuit. The only thing that didn't work was the LED in the switch. That never turns on which is strange because if the load is turning on that means current is passing through the LED in the switch right? I am using jumper wires and my load draws like .5A so the current limitation of the wires (I am assuming around 2A) shouldn't be an issue cause I hope as heck the switch doesn't consume more than 1.5A lol! What do u think is happening?

 

The only thing that didn't work was the LED in the switch.

What is the switch voltage and is it AC or DC?

I think that is it... I think it is AC and I am using a battery. These datasheets are so confusing to me. they said voltage rating VDC = 28V so I thought DC works. But then they said "Rating from 10A, 250V ac up to 20A, 277V ac", so I am guessing it is AC Thank you!

The datasheet (there is nothing really confusing about it, you just don't understand it) shows a gas lamp (likely neon) symbol (2 lines and a dot ) not a LED. There normally is a DC and AC rating for a mainly AC switch contacts with the DC rating usually much lower in voltage/current due to contact arcing when breaking DC currents. Buy a proper DC switch with a LED indicator.

You are right, I don't understand it but I spent some time on it and I think I can read it better now. Thank you! I will get a DC one
