Brake line leak

Hi all, Bob here, 68 Sprite, dual line brakes. Leak is actually at the brake failure switch, four lines going into unit are all tight. The wire from switch was originally missing and was not going to replace but fluid is leaking directly out of the end. Will replacing this switch solve the leak alone, or does this mean that the union could be bad? Union was refurbished and in working order when replaced and wasn't worried about the warning light. Can the switch be removed and just plugged up since I don't care about having the light? Any thoughts? Where to buy replacement switch if I need to?

Thanks, Bob
 
The switch does not form an air tight seal. Inside the unit is a spool that has o rings on it that are probably leaking and need to be replaced. That spool has an indented spot in it that the switch normally rests in, but if the pressure between front and rear should be different (a leak in one) the spool is moved by the unequal pressure to one side which makes the switch and gives the warning.
