Hi and welcome to my listing for this special Carling 3-position switch with solder lugs.
(See my other listing for the same switch but fitted with 1/4" spade terminals).
Suitable for most valve amplifiers that use a single standard 1/2" toggle power switch where you want to add a standby function WITHOUT drilling any extra holes.
Double pole, triple throw progressive switching controls two separate circuits giving:
Down position - both circuits open (OFF)
Middle position - circuit 1 closed (ON), circuit 2 open (OFF)
Up position - both circuits closed (ON)
Circuit 1 switches the live side of the incoming mains supply. Circuit 2 switches the HT supply.
If you don't understand the above, please get an experienced amp tech to fit this switch.
The switch is supplied loose, in a plastic bag, with a length of heat shrink tubing, and no instructions. However, I can supply a simple wiring diagram as a pdf file via email.
