SUMMARY

The discussion focuses on finding suitable alternatives for Ronway relay switches, specifically the Ronway RWG1-DC12V-HS (4-leg) and RWG1-DC12V-ZS (5-leg). The key difference between these relays is that the RWG1-DC12V-HS is a Single Pole Single Throw (SPST) relay, while the RWG1-DC12V-ZS is a Single Pole Double Throw (SPDT) relay, necessitating all five terminals. Users are encouraged to cut off the unnecessary leg if change-over contacts are not required. The JQC-3FF relay is also mentioned as a potential alternative.

PREREQUISITES
  • Understanding of relay types: SPST and SPDT
  • Familiarity with relay specifications, including voltage and current ratings
  • Knowledge of relay pin configurations
  • Basic electronics principles related to switching devices
NEXT STEPS
  • Research the specifications and applications of the JQC-3FF relay
  • Explore alternatives for SPST and SPDT relay configurations
  • Learn about relay switching principles and their impact on circuit design
  • Investigate the differences in performance between 4-leg and 5-leg relays
USEFUL FOR

Electronics enthusiasts, engineers, and hobbyists looking for relay alternatives, as well as those involved in circuit design and configuration of switching devices.

hi can anyone here recommend an alternative relay switch x2 one has 5 legs one has 4
im not able to find any the same :(
and the ones I've looked at all have 5 legs
the diffrece is Ronway RWG1-DC12V-HS
and Ronway RWG1-DC12V-ZS

Any help is appreciated :) hs and zs is the only diffrence i can see but no idea of the diffrence just the 5 leg and 4 legs.

The 5 pin relay is standard.
If you don't need change-over contacts, cut off the leg you do not need.

ok thankyou the bit that stumped me a little is the
15A 125VAC
10A 250VAC
10A 30VDC
non of what i find has the 10A 30VDC
 
cool thankyou but are these not two diffrent relays as one ends in ZS and the other in hS (HS being the four legged one) that's what made me think they are not the same ?

The relays are different. One is SPDT, and needs all 5 terminals on the package.

The other is lower cost SPST, so it is missing a pair of internal contacts and the pin that is not needed.

Do you have, by any chance, a manual for that board? I’m trying to configure a very similar one
