Pressure Switches Line Guide
Better under pressure. For years, manufacturers and operators of heavy-duty equipment have trusted Honeywell pressure and vacuum switches. They're proven under pressure, in applications constantly under attack from chemical splashes, performance spikes and other harsh environments. These switches sense a change in the pressure or vacuum, opening or closing an electrical circuit when the designated point is reached.
Honeywell offers an impressive line:
- Compact size
- Durable construction
- Enhanced set point integrity
- Customisation and modifications available
