Description
The York S1-02425986000 Control Relay is a single-pole single-throw switching part that opens or closes one circuit path in response to a 22-volt control signal, allowing the control board to activate or deactivate a connected load without direct high-voltage switching at the board output across HVAC systems. Its electromagnetic coil energizes, pulling the armature to close the single switch contact and complete the output circuit to the connected load, then releases when the coil is de-energized to open the contact and interrupt the circuit.
