Small rectangular 8-pin PCB relay with silver contacts

ProTechTrader

ProTechTrader SRC-5VDC-SH 5 V DPDT 8-pin relay

SKU CH-ZVFH-78W25 MPN SRC-5VDC-SH

5 V DC DPDT relay with 0.2 W coil power, 1 A switching capacity and 8-pin through-hole PCB mount

  • Low 0.2 W coil draw saves power
  • DPDT 8-pin switch handles two circuits
  • 1 A contact rating fits small loads
  • 1 mm × 7.6 mm pin spacing matches standard sockets
  • Gold-clad silver contacts resist corrosion

Relay for Low-Power Switching

This 5 V DPDT relay switches two independent circuits with a single coil. It is built for hobbyists and students who need a compact through-hole component for breadboard or PCB projects such as the Make: Electronics experiments. The gold-clad silver contacts handle up to 1 A at low signal levels.

Suited for Signal-Level Control

Designers who need to switch mains voltages or currents above 1 A should choose a power relay instead. The 0.2 W coil draws very little current, so it works well with microcontroller pins that cannot source high drive current. Builders requiring latching behaviour or polarised coils will need a different relay type.

Stable Operation Under Continuous Use

The coil resistance of 125 ohms limits heating during extended activation, keeping power draw at 0.2 W. Operate time is 8 ms and release time is 5 ms, so the relay settles quickly even when cycled repeatedly. Bifurcated cross-bar contacts maintain low resistance over many low-level switching cycles.

Questions about this item

What voltage power supply do I need to drive the coil of this relay?

The coil is rated for 5 volts DC with a nominal resistance of 125 ohms and draws about 0.2 watts.

Will the 5.1 mm by 7.6 mm pin spacing fit the perfboard or socket I already use for 16-pin ICs?

Yes, the DIP-2C style through-hole pins match standard 16-pin IC socket spacing for direct insertion.

How can I verify the relay switches correctly after soldering it to the board?

Apply 5 V DC to the coil pins and listen for the click; the contacts should change state within 8 ms operate and 5 ms release time.
