As my reflex programming looks to have been wiped at some point I'm trying to reprogramme my modules. One problem I have is with a fairly simple requirement.

I have a DRH (2 inputs, 2 relays) one input goes to a momentary switch (aka retractive switch) and one relay controls a light.

Now the problem with the momentary switch is that it seems to go -ve, +ve, +ve, -ve. Which has the result of toggling twice (toggle is the associated packet for the light relay) giving the following outcome:

- Press switch down, light comes on
- Release switch (switch retracts), light goes off

How can I get around this problem so that:

- Press switch down, light comes on
- Release switch (switch retracts), light stays on

(Obviously the above is from light starting in off position and going to an on position, it could equally have been light is intially on and being turned off)
