For situations thike this I usually go with a math_counter. To OR two buttons, you make the buttons add 1 when pressed and subtract 1 when unpressed. Then activate the bridge when the count is 1 or more, deactivate when it hits 0.

Edit: For a more detailed explanantion check this tutorial. It describes a setup for two buttons ANDing to open a door, but the basic concepts are the same.

@Mevious: the better solution would be using two logic_branch's and using a logic_branch_listener to activate the bridge when 'OnAllTrue' and Deactivate on 'OnMixed' and 'OnAllFalse'.

This will guaranteed work

While that method's good too, I disagree that it's any better. You can set up a math_counter with a minimum value of 0, a maximum value of 1, and an initial value of 0. Then set the outputs so that when the counter hits the maximum value the light bridge goes on and when it hits the minimum value the light bridge goes off. When both buttons are on, the counter will have a value of 2 and the light bridge will still be on.

The math_counter method wil "guaranteed work" as well, and it uses fewer entities.

Thank you very much.

After seeing the info I created for "Math_Counter" what I needed.

I also created a sample map for those who need it.
