About this item

  • 【High Performance 】:This switch latching relay is a 4 channel flip-flop relay, and low pulse module.
  • 【Self-Locking Relay Module 】:This is a bistable (self-locking) relay module, once, the relay pull (and holds); again, the relay releases (and holds).
  • 【Typical Applications】: Automotive electronics, motor, LED, smart home, emergency lighting, MCU development board, toy car.
  • 【How to Use】USE 1:By default, the relay is release, press the button, the relay pull, press again, the relay release, the third press, the relay pull, and so onUSE 2:By default, the relay is release, MCU output low-pulse(0.3-1seconds), the relay pull, low-pulse again, the relay release, the third low-pulse, the relay pull, and so on.
  • 【High Quality】:Adopted of high quality electronic components, and process, ensure for the durability,No noise was made during turning on/off, no spark, and no electromagnetic interference.

Relays don't actually latch, a transistor holds them in either state and will retain the state if power is removed but the relays themselves will revert to the default state with no power. It uses the same relays found in other modules that don't retain their state.This basically eliminates the need for a microcontroller to hold the relay open from a momentary input.
