SUMMARY

The discussion centers on the existence of a Single Pole Double Throw (SPDT) switch that reverses its position when energized or de-energized. Participants confirm that latching relays fulfill this requirement, functioning effectively in low voltage DC circuits. These relays, also known as alternating relays or contactors, are commonly utilized in alternating pump ejector systems, providing a reliable solution for the specified application.

PREREQUISITES
  • Understanding of latching relays
  • Knowledge of low voltage DC circuits
  • Familiarity with SPDT switch configurations
  • Basic principles of relay operation
NEXT STEPS
  • Research latching relay specifications and applications
  • Explore the design and implementation of low voltage DC circuits
  • Learn about alternating relays and their operational principles
  • Investigate contactor types and their uses in automation
USEFUL FOR

Electronics engineers, hobbyists working with low voltage DC circuits, and anyone interested in relay technology and automation solutions.

I'm wondering if there is such thing as a spdt which reverses upon being energized/de-energized? So each time a voltage is disconnected then reconnected the switch flips once and locks in place till the next disconnect/connect.

I'm interested in this for a low voltage dc circuit.

Yes, there is such thing. Look under latching relay.
 
they are used in alternating pump ejector system and are called alternating relays or contactors.
