Lever Lock toggle switch selection

I need an SPST lever-lock panel mounted toggle switch rated at 30Amp. Can you please suggest a part number?

Locking actuators and a 30A+ current rating are both relatively uncommon features, and I’m not finding any single product offering both. A possible solution may be to separate those, using a switch with locking actuator to control a relay of appropriate ratings; note that the voltage being switched is relevant to relay selection, and needs to be taken into account.
