Carling Rocker Switch (V-series) P/N’s Explained
Below we’ll explain everything you ever wanted to know about Carling V-series options and part numbers
Have you ever been stuck trying to find the correct V-series Carling rocker switches (often called contura)? You’re at the right place. We’re going to walk through the sometimes complicated, yet incredibly useful part number scheme.
We’ll explain what each digit means, and what the options are. We’ll discuss how to find a suitable substitute for a hard to fine Carling rocker switch. And We’ll walk through some example part numbers.
1 – Carling V-Series Spec Sheet
You should probably start by opening the spec sheet in another tab. Skim over it real quickly.
Lots of info, right? We’ll be focusing on the part number scheme on page 10 primarily with some reachback to page 8 and 9 (the circuit diagrams).
Over 250 million switch options available!
If you look at page 10, you can see Carling has a TON of options. Digit two allows 22 different circuit styles. There are 14 different base styles in digit four, and 32 different illumination styles in digit five!
In fact, a little math tells us there are over 250 million possible part numbers in the first 8 digits alone (272,498,688 to be exact).
1.A – Inventory and Market Availability
250+ million possibilities! How in the world does Carling stock all those part numbers?
Carling does not stock any inventory
Well, they don’t. The product is so flexible, with so many options, Carling manufactures switches to order from distributors like Rocker Switch Pros, or other system manufacturers. When any system, be it a generator, or tractor, or 4-wheeler, or boat is designed, an engineer specs a certain part number by looking at the spec sheet.
They order 500, or 1,000 or 10,000 or whatever number of rocker switches they need, and Carling builds and ships them. The flexibility is awesome, but can create havoc for you when you go to replace a single switch. Unless some distributor has ordered a case of them, the it could literally be impossible to find for sale (in volumes of 1 anyway).
Obviously you don’t want to pay for a case of custom manufactured switches to make the awning retract on your RV. That’s where we come in. Once you walk through this Carling rocker switch guide, you’ll be able to find and select the switch that meets your requirements from an endless sea of possible parts.
2 – Carling Part Numbers
This is the full Part number scheme:
However, were going to talk just about the first 8 digits today. The last 6 digits talk about the actuator, but because we sell the actuators separately (plus it complicates matters) from the switch bodies, we’ll only address the digits pertaining to the rocker switch body:
