Guy's I'm fitting out Conqueror with two mk8s. The torpedo release for both tubes is a simple servo pull connected to a steering arm. Either side of the steering arm activates the tubes via a 3 position switch on my radio.. i.e. centre - the steering arm is at rest, toggled one way I get steering arm releasing one tube, toggled the other way releases the other.
On the odd occasion -I find turning on the Subdriver can cause servo jitters - and whilst if this does occur in my case this lasts less than a second, it is enough to potentially cook off a shot unintendedly. To counter this, I have a mechanical safety set up in the boat. Should the steering arm that activates the torpedos jitter as I turn the Subdriver on, the arm located below the pull mechanisms won'’t engage the release pull mechanisms until I insert a couple of drag pins held by gravity into the back of each servo release pull. With the pins inserted if the servo arm moves backwards the servo arm engages the pins and pulls the torpedo release. Suffice to say I always turn on the boat first before arming the release mechanisms.
Whilst I have used that mechanical safety now for years, I’m wondering if I can add an electrical safety?
My idea for this was using a channel spare whereby I could rig up a simple microswitch connected to a micro servo. The microswitch could either make the servo controlling the torpedo switch either active or inactive.
Question is, is it enough to simply route the positive lead from the torpedo servo through the microswitch or do I need to do something with the signal and ground as well?
Cheers
