Traditions (Generic) Computer Power Cord DC 12V Timer Switch Module

SKU CH-7GTX-344JN

A DC 12 V timer switch module provides adjustable delay-on and delay-off control for computer power cords

  • DC 12V timer switch automates power sequencing
  • Delay-on and delay-off functions protect equipment from surges
  • Relay module integrates into custom 12V DC control circuits
  • Compact timer relay suits hobbyist and industrial automation projects

DC 12 V Timer Switch Module

This DC 12 V delay relay provides programmable turn-on and turn-off timing for low-voltage circuits. It suits hobbyists, technicians and system integrators who need automated power sequencing in custom builds or test rigs.

Adds timed switching to existing 12 V wiring

The module replaces manual switching or basic relays that lack delay functions. The upgrade is worth it when a project requires staggered start-up, controlled shutdown or repeated cycling without adding a separate microcontroller.

Questions about this item

What mounting holes or brackets does the DC 12V timer switch module include for installation?

The module is a compact relay board designed for inline wiring; it has no dedicated mounting holes or brackets, so secure it with cable ties or double-sided tape inside the enclosure.

How is the timer module wired, and which step do installers often get wrong?

Connect the 12 V supply to the input terminals and the load to the output terminals, observing polarity; the common mistake is reversing the trigger and load wires, which prevents the delay function from operating.
