Single Pole Double Throw Relay
A single-pole double-throw relay connects one common contact to either of two alternative paths according to its actuation state.

Product & engineering
Understand the product.
SPDT describes topology rather than interruption timing; break-before-make behaviour, ratings and isolation depend on the selected design.
What turns activity into demand
Switching requirements translate into poles, load duty, isolation and control interfaces. Replacement decisions also depend on contact wear, operating cycles and the surrounding protection circuit.
The commercial boundary
Mechanical-contact and semiconductor relays have different loss and failure behaviour. Coil supply or package similarity alone does not establish interchangeability.
What happens when actuation power is removed?
SPDT describes topology rather than interruption timing; break-before-make behaviour, ratings and isolation depend on the selected design.
