Answer:

Fail-close

Step-by-step explanation:

A failed open switch is a switching device (be it mechanical, relay, semiconductor) that has lost it's switching capabilities (it's defective) and the switched contacts are now constantly open (disconnected) regardless of the control signal to the switch.

Similarly a failed closed switch is the same just with the contacts connected through.
