Switchy is the switching hub in the Camper Jarvis system. Eight channels in one board: four for 12V and 24V loads, four for 230V. Pumps, fans, boilers, sockets and even lifting beds are switched from one place, from the SmartKnob or the dashboard, entirely local in the vehicle with no cloud and no app required.

Good to know: Switchy switches, it does not measure. If you want to see what an individual load draws, that is what Ampy is for; battery and system data come from Volty. The three work together in one dashboard. Wall push buttons go on Ampy or Lighty, Switchy has no push button inputs.

Highlights

  • Eight channels in one board: 4 DC up to 30A and 4 AC up to 10A each
  • Shore power detection with fault check for swapped live and neutral or missing earth
  • Automations on shore power: boiler on when you plug in, off when you leave
  • Motor control with direction interlock and two end-position inputs
  • Only 0.71W in normal operation, 2.26W with all relays pulled in
  • Every channel individually named in the dashboard
  • Tool-free spring terminals, no crimping and no soldering
  • Operated from the SmartKnob or the dashboard, entirely local without cloud

Product Specification

Switchy at a glance

Real install Switchy in the technical compartment, with four DC and four AC channels.
Switchy in the technical compartment, with four DC and four AC channels.

8 channels, DC and AC

Four channels for 12V and 24V up to 30A each, four for 230V up to 10A or 2300W.

Detects shore power

Switchy notices when you plug in at the campsite and can switch the boiler automatically, for example.

Checks shore power

If the earth is missing, Switchy switches all 230V channels off within milliseconds. It also tells you when live and neutral are swapped.

Lift bed and pop-top roof

Direction interlock for 12V, 24V and 230V motors. Two limit switch inputs stop the motor at its end position.

Push-in instead of crimping

Every wire goes into tool-free spring terminals. No crimping, no soldering.

Low consumption

Only 0.71W in normal operation and 2.26W with all relays pulled in.

Frequently asked questions about Switchy

What can I switch with Switchy?

Up to eight devices from one place:

  • 4 channels for 12V and 24V, each up to 30A, for example a pump, a fan or a lift bed
  • 4 channels for 230V, each up to 10A or 2300W, for example a boiler or sockets

Appliances that draw much more, such as an air conditioner, a tumble dryer or an induction hob, do not belong behind Switchy. They get their own circuit breaker in the 230V distribution.

More on this in Switching loads with Switchy.

Can I connect wall push buttons to Switchy?

No, Switchy has no push button inputs. You switch its channels on the SmartKnob or in the dashboard, also on a schedule or as part of a scene.

If you also want to switch a device at the wall, connect it to Ampy or Lighty instead. There you can connect a push button to every output.

Does Switchy show what my devices consume?

No. Switchy switches, it does not measure. Ampy measures what each individual device draws, output by output. Battery and system data come from Volty. All three work together in the same dashboard.

Which fuses do I need for Switchy?

Switchy has no fuses of its own for the connected devices; they belong in the installation:

  • 12V and 24V: each channel gets its own fuse in the positive cable, no more than 30cm from the battery's positive terminal.
  • 230V: a 30mA residual current device and a B10 circuit breaker sit in front of Switchy.

Only a qualified electrician may carry out the 230V installation. Why it has to be a B10 is explained in Why a B10 circuit breaker is needed at 230V.

What happens if the shore power pillar is wired incorrectly?

Switchy checks the shore power continuously and shows you on the SmartKnob and in the dashboard whether everything is in order.

  • If the earth is missing, Switchy switches off all four 230V channels within milliseconds and the SmartKnob raises an alarm. Once the earth is back, you switch your devices back on yourself. That way nothing starts up unattended.
  • If live and neutral are swapped, it is almost always down to a Schuko plug or adapter. Pull the plug, turn it by 180 degrees and plug it back in.

All the details in What the AC input monitoring does.

Can Switchy react automatically when I plug into shore power?

Yes. Switchy detects whether shore power is present, and you can use that as a trigger in the dashboard. For example, the boiler switches on as soon as you plug in at the campsite and off again when you unplug.

Can Switchy move my lift bed or pop-top roof?

Yes, with a 12V, 24V or 230V motor. Switchy electronically prevents both directions from being driven at the same time.

For this, Switchy has 2 inputs for limit switches, usually magnetic reed contacts. When the mechanism reaches its end position at the top or bottom, Switchy switches off the corresponding 12V or 24V channel. You set in the dashboard whether you use a normally open or normally closed contact.

How to connect the switches is explained in Connecting limit switches.

Does Switchy work on 12V and 24V?

Yes. Switchy runs on a supply from 9 to 36V, so it fits both 12V and 24V systems.

How much power does Switchy itself use?

Very little. 0.71W in normal operation, that is 56mA at 12.7V. Even with all relays pulled in, it is only 2.26W.

That is because Switchy pulls in each relay with full current and then holds it with a much smaller holding current.

What is included with Switchy?

Switchy, 4 mounting screws and 3 two-pole pluggable spring terminal connectors: one for the power supply and two for the limit switch inputs. Every wire goes into tool-free spring terminals, no crimping needed.
