LED with good visibility for vacuum switch display.
- To improve visibility, an LED display is adopted for the vacuum switch
- LED displays are used for set-up pressure and working pressure
- 2 points signal output type and 1point signal output with 1 analog output type is available
Selection by applications is possible. A connector wiring realize easy layout.
- Output detection accuracy is enhanced by the use of semiconductor switch
