Click For Summary
A latching relay can function as a single pole double throw (SPDT) switch that reverses its position when energized and de-energized. This type of relay locks in place after each voltage disconnect and reconnect, making it suitable for low voltage DC circuits. Common applications include alternating pump ejector systems, where they are referred to as alternating relays or contactors. These relays provide a reliable solution for switching tasks that require a toggle action with minimal manual intervention. Utilizing a latching relay can enhance the efficiency of low voltage DC applications.

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.
 

Thread 'Electric power distribution from powerplant to homes'

I am trying to understand how transferring electric from the powerplant to my house is more effective using high voltage. The suggested explanation that the current is equal to the power supply divided by the voltage, and hence higher voltage leads to lower current and as a result to a lower power loss on the conductives is very confusing me. I know that the current is determined by the voltage and the resistance, and not by a power capability - which defines a limit to the allowable...
