Semi Truck A/C Control Switches

While the product work for a little while, it failed after five minutes of operation. This switch went on a 1987 Ramcharger with factor hoses but it is not "dampened" as the factory unit is. There is not an orifice within the switch to slow down it dampen the switch operation. Maybe the addition of an oirfice might work but have no idea of the size to provide the dampening. It appears that no one makes this dampened switch anymore so I am still searching.
