Top 10 Latching Relay Manufacturers & Brands
A latching relay (aka impulse relay) controls a heavy amount of current flow. It retains its position after being actuated without needing continuous power. “Latching” refers to its ability to maintain its state (on or off) after a momentary impulse.
These relays are used for light and HVAC controls and automation in homes (or any residential setting), commercial, and industrial settings.
The demand for latching impulse relays is rising because of their wide use, efficient energy control, and smart automation. As more industries and households adopt sustainable practices, the need for reliable, low-power switching devices grows.
