Another 12070 query

I know this topic has come up on several occasions before, but I couldn`t find a schematic showing how to wire up the 12070 supplementary switch to operate signals in conjunction with point movement. So could some kind soul confirm that what I`m proposing to do (shown below) is correct? (Note - I run Massoth so track voltage is 23V, the "Green" and "Red" in the diagram are LEDs with appropriate resistors already attached)



Also, in view of comments about the microswitches failing, I circuit tested mine with a multi-meter and found that the two connections nearest the middle (numbers 3 and 4) don`t appear to do anything. There is no continuity between them or either of the input connections (numbers 2 and 5). Number 1 works with Number 2, and Number 5 works with Number 6 but that`s it. As this is the same on 3 new switches I assume it`s designed this way. Could someone perhaps explain what the point of these "dead" connections is?

Many thanks
Phil

Hi Phil,

The 12070 contains 2 micro switches, one is connected to terminals 1, 2 & 3 with 2 being common. 1 & 3 are switched based on the position of the point motor. Likewise with 4, 5 & 6 with 5 being common.

If the 12070 is good then you should not need to connect 2 & 5, just 2 and the cable from 6 would be to 3.
