Please use the Drools forum for your questions, as you will get a lot more help there:
If you are a Red Hat BRMS subscriber, you can use the customer portal for support.
Also, please clarify your question, maybe with an example of what you are trying to do. I am not sure what you mean by "create a ON/OFF toggle using BRMS".
I am just trying to create a switch to enable something in my code.
