MK2 Lever Frame, microswitch, dapol signal

Postby TEZBEDZ » Wed Sep 23, 2020 8:05 pm

Wondering if someone can help.
I have built a MK2 lever frame, (15 levers in fact)fitted with Microswitches.
I have been given a Dapol signal, to use it in an on/off mode as opposed to pulse I have fitted a merg upgrade.
The problem is the normal state (signal at danger) for the merg unit is powered ie with the lever pulled.
Is there a way to change the switch to reverse this.i can't change the polarity of the merg board.
Regards

Then use the other contact on the micro-switch.
