Jabsco Pump Replacement Pressure Switches

The switch 'clicks' when the pressure button is pressed so I suppose it works. However, the package had been opened and neatly taped closed. Someone harvested the two attachment screws and the blue covering cap screw. I know this because fortunately, I'd bought two switches and the second package had all of the screws in it. I'll find replacement screws along my travels but for the price of each switch, the bag containing the switch really should have been double checked to make certain all parts were in the parts bag BEFORE it was shipped to a customer. I'm also out sailing so my order was shipped international once it left Jamestown Dist.
