What is the function of latching relay?

What’s a latching relay? It is a relay that is set (ON) or reset (OFF) by the input of a pulse voltage. Even after the input voltage is interrupted, this relay maintains its set or reset condition until it receives the next inverting input.

How do you reset a latching relay?

Resetting is very simple. The coil circuit needs to be opened and shortened to the coils ground potential. The capacitor will be discharged through the coil and drives a current pulse with opposite polarity through the coil, that resets the relay (Figure 4).

What is a latching relay instructions?

A latching relay is a two-position electrically-actuated switch. It is controlled by two momentary-acting switches or sensors, one that ‘sets’ the relay, and the other ‘resets’ the relay. The latching relay maintains its position after the actuating switch has been released, so it performs a basic memory function.

What is the difference between a latching relay and a normal relay?

Similar in functionality to a latching relay but with an obvious difference, a latching relay will stay in it the position it had when it was last powered up, but, a non-latching relay returns to its normal position when power is removed.

How does the relay turn off the headlight?

The relay switches the headlight off during cranking, and that’s all. NOTE that the high beam flasher function remains, due to a separate green wire from the ignition switch, as a separate circuit. The headlight relay may or may not turn off the headlight, during engine cranking, depending on year, model, & country shipped-to.

What kind of plugs are in a motorcycle headlight relay?

The harness includes two high-quality Matsushita automotive grade 20-amp plug-in relays, each protected by a heavy plastic water resistant cover. It’s pre-wired with H4 male and female headlight plugs and 14 gauge power and ground leads that have eyelets correctly sized for most motorcycle battery terminals.

How to wire a headlight enhancement relay kit?

This video is a detailed walkthrough of the American Autowire headlight enhancement relay kit. Our kit includes separate relays for the high and low beams as well as upgraded GXL wire to make fresh connections to your lights. It’s available in both standard (pn/ 500403) and weatherproof (p/n 500431) form. Loading…

When does the headlight switch off during cranking?

The stock headlight relay from 1978 also does notswitch between high or low beams. The relay switches the headlight off during cranking, and that’s all.
