Jumper the switch. Connect a jumper between the two spades and that should give you continuity to the lights with your hot lead.
You will be effectively closing the switch as if you had applied brake pedal pressure to the hydraulics..If you have lights then, your wiring is fine, but the switch is toast.
No need to push on the brakes with this test.
Another check is to take the leads off the switch connect a meter to the spades using ohms set on resistance..pump the brake now and see if the switch is closing ( low to 0 ohms ) and reading Megaohms when no brake pumped
