Custom Pressure Switch for the Pump Industry

Client Requirements: Our client came to us with a pressure switch that did not meet their functional as well as aesthetic requirements for a water pump application. 

Our Solution: Thus, we analyzed the application, understood the requirements for the pressure switch and identified areas of improvement for the product. We then prototyped a switch for the customer to evaluate. The switch had to fit within a specific assembly with extremely tight tolerances, maintain WRAS approval, and be able to withstand moderate pressures. We performed pressure testing and cycle testing of the product in-house, and had a third party lab verify any tolerance requirements necessary.

Furthermore, we constructed an entirely new assembly line and set up specific manufacturing procedures for this client to ensure that the delivered product would meet all their requirements. Not only did we improve the existing switch, but we discovered additional improvements to create a more efficient overall assembly for our client.
