There are lockers for luggage at many Swiss train stations. I would like to store luggage in one of them (in Brig) for three days, buy cannot find out what the maximum period for rentals is - does anyone know?

It appears that information is in fact not listed in full on public websites.

So I called them and asked about specifics at the Brig train station:

Storage duration

• Generally, the maximum storage duration is 24h


• However, you can extend the storage duration via supplementary payments before the 24h runs out, up to a maximum of 72h total
  


• If a 24h period runs out without further payment, the contents will be locked and a red light on the locker should indicate that you need to pay again to access your contents


• After the total maximum of 72h runs out, the contents of the locker will be claimed by the baggage office and moved to the lost & found, and you'll have to pick them up there (for a fee, I assume)

Pricing

Prices and available sizes do vary between locations (source (german)).

In Brig, there's two sizes of lockers (width x height x depth):

• 
  Large - 44x61x88cm - CHF 8.00 / 24h


• 
  Small - 24x42x75cm - CHF 5.00 / 24h

Note: These opening times only refer to the offices (baggage / lost & found), access times for your locker are usually longer.

I couldn't get exact details for access times to lockers in the Brig station, but this page for lockers in Zürich main station lists them as

Sat–Sun 24h
Mon-Fri 00.30–04.30 closed

so I assume the situation in Brig is at least similar.
