A bit confused re connecting the 4TS3 Push-button with led to an OP Master Card output
I am building a OP MCP and use the OP Master Card as output to LEDs.
I plan to use the 4TS3 Push-button with LED and wonder if I need to connect a resistor in serie with the LED in the 4TS3? I guess I have to connect the Cathode of the LED to the common GND and the anode to the Master Card output after a resistor (if needed) , but I don not know which of the 2 pins on the 4TS3 is the cathode. I only have the excact number of items, so I want to avoid burning and be sure before I connect.
Could anyone help me out on this one?
