SKU CH-YXJD-P1V1J

Provides a 12 V bistable relay for car one-key start and stop modifications

  • Bistable relay keeps circuit state without constant power
  • 12 V supply suits standard automotive electrical systems
  • One-key start and stop simplifies vehicle control
  • Self-locking action holds position until deliberately changed

Automotive relay module for 12V switching

This 12V bistable relay module provides a self-locking switch function for car modification projects. It enables one-key start and stop control without continuous power to the coil. The module suits builders adding custom ignition or accessory switching to a vehicle electrical system.

Low standby draw with latching operation

Because the relay holds its state without coil current, power draw drops to near zero when the circuit is latched on or off. No active cooling is required and the device runs silently during normal use. Thermals remain negligible in typical automotive wiring environments.

Questions about this item

How do I wire the 12V bistable relay module for a one-key start and stop function?

Connect the module to a 12V power source and the vehicle's ignition circuit; the self-locking design toggles state with each pulse, so ensure the trigger wire receives a momentary signal rather than constant voltage to avoid unintended cycling.

What maintenance does the 12V bistable relay module require over time?

The solid-state bistable design has no moving contacts to wear out; periodically check that the power and trigger connections remain tight and free of corrosion to maintain reliable one-key start and stop operation.
