air bag activation switches - reusable?

Anyone know if the air bag activation switches located at the front bumber on a 98 Windstar are reusable after they activate and then the bumber is returned to its original position, or is this type of switch a "one time only" type of switch? There is no real bumper damage and the switches are intact.

According to the collision estimating software, only the airbag module under the dash needs replaced after the airbags have be deployed. This is of course if all the other sensors were not damaged.
