We often have customers ask if there is a way to illuminate the lamp with a separate signal to light up all the symbols on our labeled switch actuators.
Well, this is possible through the use of an independent lamp switch body (New Wire Marine caries two varieties of carling’s independent switch type). An independent lamp rocker switch (see it here) has a fourth terminal on the back, that when applied with 12V will light up, without actually having the switch in the ON position.
The standard dependant lamp switches (see them here), only illuminate the lamp when in the ON position.
I personally prefer dependant lamp type switches. This is because when you trigger the lamps independently, you really can’t make out the symbol at night anyway, so a better option is to install some kind of helm light (use red color so it doesn’t screw up your night vision). Also, if you trigger the external light, you loose the indicator of whether or not the switch is actually ON… as the lamp is always illuminated, you could run your bilge dry, or leave your stereo on, etc, without realizing it.
