According to
this thread, 3'800-4'200 CHF/month gross and full time is common, but the numbers are from canton Aargau and might be a bit dated. Also it depends on qualifications and diplomas... I quoted a single source, treat it like that.
You can find job offerings at the non-profit organisation of the canton
here. According to the national non-profit umbrella organisation, the majority of home care employees work part-time.
