Bluewater P/N: 9055-2118

Our Bluewater Signal Switch is called that because it has a very specific use case: switching VERY low (<240mA) current signals.  Please understand it’s use, and do not use it as a standard switch.

It is most commonly used for interfacing with digital switching systems like POCO’s S8, C-Zone, Garmin EmpirBus, Marlin, etc.  Because these systems do not pull load current, they are just looking for a high/low signal needed for their control boxes.

For this reason, they are momentary only.  There is no latching signal switch version currently available.  This is normal for most digital switching systems, because a pulse signal is what the controller is looking for (otherwise, the switch would be in the wrong position if you turned it on from the physical switch, then off from the virtual switch – think like a rocker switch here).

These switches are great to add remote physical switches to a digital switching system’s commonly used loads so you can keep your MFD on something else and still operate your devices (a common annoyance).

This switch contains standard bright LEDs, which will match intensity of 9055 and 9058 series switches.  We also have a DayBright version, which will match intensity of 9059 and 9060 switches.

It is dry contact – not solid state, so it can switch basically any DC operating voltage (up to 30Vdc), OR a negative signal.  It’s LED’s (there are two emitters) have a side voltage input range as well (3Vdc – 24Vdc).  That makes it very flexible, and can be utilized by basically all digital switching systems known to us.

This is a switch body only.  You’ll need to order separately a laser etched or stainless 22mm switch face, and a dual output connector plug for a fully functioning switch.

The pin layout on this switch is different than other Bluewater switches because it has two independent LED’s with a common cathode (negative pin).  No lights will come on if you don’t connect pin 4 or 2 (see product photos or spec sheet above).  A common use case for this switch would be to wire pin 4 to your panel backlights for blue backlighting at night to match the rest of the switch bank.  Then wire pin 2 (red) to the output of the digital switching system, so that it feeds back to turn the switch red when a virtual switch is touched on the MFD.

Note, that there’s no microcontroller in these switches, so the blue light does NOT turn off when the red light is active.  So if the blue (pin 4) and red (pin 2) are both active, then both colors will shine making purple.  This actually is a rather nice color in our opinion, and makes for an easy way to tell which switches in your bank are directly feeding current, and which are remote digital switching switches.

Note also that there is NO circuit protection built in, it is very easy to fry the switch if you accidentally short the terminals (pins 1 and 3) for even a split second.  For this reason we cannot replace under warranty signal switches that are ID’d as failed due to overcurrent.
