C .Sliding valve closes, vacuum generator stops working

2. customer troubles

A .The vacuum degree inside the sewage collection pipe is insufficient, and the toilet cannot work properly.
B .The road conditions were poor, and the low current gold contacts were contaminated with impurities, causing the vacuum switch to burn out.

C.The climate and environment differ greatly between the north and south, and domestic vacuum switches cannot work properly.

3. Solution

A . BECKVacuum switch vacuum pressure range-5mbar~-900mbar,Wide vacuum range.
B .Replace low current gold contacts with high current silver contacts, which have low conductivity and solve the problem of vacuum switch burnout.
C . BECKVacuum switch temperature range -20°C bis +85°CThe lifespan of the switch exceeds100Ten thousand times.
