We have a pair of WLC 5520s in an active/standby configuration. Both are up, but it looks like there was a failover to the secondary at some point. If I do a 'redundancy force-switchover' on the secondary, how disruptive will this be to our wireless users? We have around 1260 APs.

HA Switch over not distruptive as long it configured correctly.

Anything I should check for before doing it? I'll probably do it after business hours.

- If there was a failover to the secondary then the reason should probably be known and or the the health-state of the (previous) primary should be inspected , look for crash-logs (e.g.). But in normal circumstances there is no impact and it is even safe to do in business hours.

Make sure HA is Health before failover - no obnormal logs and fail over.
yes it is always advise to do in maintenance window for safe and good approach to cover yourself.

If the failover state is healthy (and assuming you haven't changed anything in the networking setup on the switch side since setup and testing) then there is no interruption at all when switching over at least for data transfers. Never tested if voice calls have a jitter when doing it.
