DUNGS LGW and GW pressure switches group differential and compact pressure-switch families for burner air and gas supervision. The LGW A2 and A4 ranges focus on differential pressure control, while GW A5 and A6 compact switches provide selectable mbar ranges with switching-difference data for service comparison.
