Thread: Dual Transducer Switch HB

The TS2 (and TS3) switch does not "power" the xducers in any way ...(if the head unit is off - the xducers are not pinging) ...

The 12v power source only energizes the relay actuator that allows sonar data to flow down one of the 2 legs going to the xducers ...

The relay and actuator are in the epoxy filled pod looking thing at the "Y" of the xducer cables ... It's kinda like a railroad track actuator ...where the actuator simply directs which xducer cable the sonar data is to pass thru ... But it takes 12v power for the relay to move the actuator into position 1 or position 2 ...

The TS2 (old design) has the relay (in the epoxy filled pod) energized constantly ...regardless of which way the toggle is selected ...

The TS3 (new design) has the relay (in the epoxy filled pod) energized in only one of the toggle positions ...
