FAQ02817 of General Purpose Relays FAQ

Yes, but problems may occur depending on the load conditions. If different currents are applied to the Relay, do not have it simultaneously switch a large load and a microload, and do not use the Relay in a circuit with a difference in electric potential across the circuit.

The purity of the contacts used for microload switching will be lost due to the contact spattering that occurs when switching a large load, and this may cause contact failure when switching a microload.
