Vacuum pumps
This product is designed to create vacuum in the brake boosters of electric vehicles. It includes an electronic pressure switch (Type 70/6E relative pressure measuring sensor) (Type 70/6E2 absolute pressure measuring sensor) that turns off the pump when the vacuum in the booster reaches a customized maximum value. It also includes a one-way valve to maintain the vacuum in the booster. The hysteresis of the pressure switch can be changed on request.
