I just called dimension E, they said they are working on a programmable version of the pico/battleswitch line that should come out some time next year.

because I have to stack 15 functions onto a 12 channel 433MHz radio system (Dragon Link) and Tarranis 9. Thus i’m going to use one of the 3 way switches which are 1000us down (on), 1500us off, 2000us up (on). Down will turn on visible light and up will turn on infrared. Thus using the DPDT relay board, I can use the inverted polarities to turn the LED’s on/off.

Or if dimension engineering can make a picoswitch that is on at 1000-1480 and off from 1520-2000 (reverse of current version), that would work too.

A1 throttle / brake ………… (right joy vertical) – no spring
A2 steer ………… (right joy horizontal)
D1 boom tilt up/down ………… (digital 1) (on-off-on)
A3 boom rotate left/right ………… (right knob)
A4 camera tilt up/down ………… (left joy vertical) – no spring
A5 camera pan left/right ………… (left joy horizontal) – no spring (both pan servos on Y cable)
A6 claw arm up/down ………… (front slider 1)
A7 claw arm rotate ………… (front slider 2)
A8 claw open/close ………… (left knob)
D2 crabsteer/countersteer and cargo bay door ………… (digital 2) (on/off/on + picoswitch + DPDT relay + programmable servo)
D3 visible lights on/IR lights on ………… (digital 3) (on/off/on + DPDT board)
D4 Video Camera A/B Switch …………. (digital 4) (on/off/on)

That doesn’t answer my question. Will my description above work by connecting my visible and InfraRed LED arrays to M1 and M2 as described?

seems to me that the SPST relay is powered on (darlington sink) by any non-neutral value, and the DPDT relay is powered on (darlington sink) on a <1.5ms signal. The SPST relay switches the hot lead going to the DPDT center contacts, and the DPDT has the X arrangement for reversing output polarity.

Say, for my situation, I want 1-1.4ms to turn on my visible light LED array, 1.6-2ms to turn on my IR LED array, and for both to be off in the 1.5ms neutral zone.

If I treat the DPDT relay as a logical rectifier, then I can connect the positive side of both arrays to +12V, the ground side of visible light to M1, and the ground side of IR to M2.

If my rough idea is correct:

When M1 is 12V and M2 is ground, the IR should light because high side has voltage and low side is grounded. Visibile should stay off because high side has voltage and low side has voltage.

When M1 is ground and M2 is 12V, then IR should stay off because high side has voltage and low side has voltage, and visible should come on because high side has voltage and low side has ground.

Is this correct?
