Yeah, that's the only way for a temporary fix.
But replacing it will involve removing the steering wheel. IT'S NOT THAT TOUGH. Just make sure the front wheels are straight before you remove the steering wheel and the brakes are set.
Then remove the steering wheel with a puller and replace the switch. If you do not have a steering wheel puller, your local parts house SHOULD loan it to you. You will have to give them a deposit, but as long as you don't break it, it should be free.
