YOSHINE Double Trigger Single Time Relay
An SPDT off-delay relay offers a simpler contact arrangement while still providing reliable delayed release behavior. In this design, a single pole switches between normally open and normally closed contacts when energized, and after the trigger signal is removed, the relay holds its last state for the set delay time. Once the delay ends, it resets automatically. This type is often chosen for compact control circuits where only one switching path is required, such as alarm systems, lighting controls, or small automation modules. The off-delay action helps prevent nuisance shutdowns caused by brief power interruptions or signal fluctuations. Compared with DPDT versions, the SPDT off-delay relay is more space-efficient and easier to integrate, making it a cost-effective solution for straightforward timing control tasks that still demand dependable performance.
