I have the Radio Shack 61-2661 Remote Switch to turn on and off the MATCHED plug in outlet. I am just trying to find the Paper Schematic for this tiny unit to repair it. The hand-held unit works but the Red LED on it does not. I have checked the led and find it is burned out. I am trying to find out the Part Number of the Red LED or the voltage value of the Red LED. Can anyone help me determine what the LED VOLTAGE is.
LEDs are usually pretty hardy. Are you sure it is "burned-out"? (it reads "open", or shorted both ways?). Technically LEDs do not have specific voltages, they are current devices, and the current limiting resistor for your LED will be on the circuit board. So all you need is another LED the same physical size. Radio Shark will likely have a red LED of the same size.
LEDs are polarity sensitive so your new LED must be soldered in the same way (polarity, or +, - lead orientation) the old came out. Look for a small flat spot on the old LED's base flange. That usually marks the cathode lead. On your new LED the cathode lead should be the longest. If no flat spot, then look at the internal structure of the old LED while it is still soldered in the board. Orient your new LED in the same manner.
