About this product
A 5-pin HELISHUN HLS-14F1L relay with a 12VDC coil and a 10A contact rating. It switches a higher-current load from a low-power 12V control circuit, which suits automation, appliance control and DIY relay projects. Check the contact voltage rating before connecting mains loads.

Frequently asked questions
How do I wire the 5 pins?
Two pins connect to the coil, one is the common contact, and the other two are the normally open and normally closed contacts. Match each pin to the diagram printed on the relay body or the datasheet before wiring.
Do I need a flyback diode?
Yes, when the coil is driven by a transistor or microcontroller. A flyback diode across the coil protects the driver from the voltage spike generated when the coil is switched off.
