| Lamb Industries 79-Series Pressure Switch | ||
      |
||
 |
The 79-Series pressure switch is suitable for air, water, or other non-hazardous environments. It can also be used in pressure or vacuum application. This switch can be preset at the factory to pressures between 15mbars ~ 2,500mbars. If higher amperages and pressures are desired, look at the M3-Series and M4-Series pressure switches. For a less expensive option try the P1-Series. |
