Pressure switches
| Types: | |
| Application | |
| The switch is suitable for switching a signalling lamp at a preset value of lubricating oil pressure or compressed air pressure of motor vehicles. | |
| Description | |
The pressure switch is of spring-contact type. It is built into a metal trunk. The medium to be measured is separeted by an elastic membrane from switching unit. The compression spring moves upon effect increasing pressure and opens or closes a contact pair. Between the given pressure ranges any switching value – according to the order – can be adjusted. |
