percarqty: 1 New Oil Pressure Light Switch Terminal Quantity : 1 In manufacturing, we utilize a laser etching system to calibrate thick film printed circuits. This method provides for high accuracy reading of actual oil pressure in vehicle€“s engine. In construction, we utilize high temperature, polyimide film diaphragms. These provide for exceptional cycle durability & resistance to rupture & oil leakage. Units are designed to handle rapid pressure pulsations, without component damage. All units are 100% tested using automated equipment that activates the switch, checks for leaks & stresses the part to ensure specification compliance, even under the most demanding operating conditions. Our switches feature a robust design with high grade materials to meet the stringent demands of todays service professional.
