The EMERSON-ASCO pressure switch is a normally closed (NC) switch covering a 0.5 bar to 10 bar adjustable range, used to trigger an electrical signal on pressure rise or fall within that band — typically for compressor control, pump protection, or process interlock duty.

Wiring configuration, electrical rating, and process connection thread should be confirmed against the exact model before installation, since ASCO offers this switch body across several electrical and connection variants.
