That's the correct operation.

When your front brake is not being used, the lever pushes the switch in and turns the light off.

As you pull the lever, it allows the little button to pop back out and turn the light on.

It's the opposite to how you would work a push switch which is what's confused you, but in operation that's how it works as operates off the back of the lever and not the front, so releases when you pull the lever, not presses (if you see what I mean).

Just fit the new switch and see if it works when in place

It is counterintuitive but stop light microswitch is closed without force applied to it. When force is applied circuit opens.
Now after you install it make sure you have brake light on at the point of actual breaking. Sometime plunger needs to be trimmed to achieve that, particularly when brakes were modded with stainless hoses
