What does a square with a darkened lower triangle represent?

AC Relay
DC Relay
Latching Relay
Timer

The correct answer is: Latching Relay

A square with a darkened lower triangle represents a latching relay. This type of relay has two stable states, requiring a pulse or change in input to switch between them. Option A, AC Relay, is incorrect because a square with a darkened lower triangle specifically represents a latching relay and not just any type of AC relay. Option B, DC Relay, is also incorrect because a square with a darkened lower triangle specifically represents a latching relay and not just any type of DC relay. Option D, Timer, is incorrect because a square with a darkened lower triangle is a symbol for latching relay, not a timer.
