I have an old lennox furnace from 1958 that has a 115 volt, continuous ignition, Max 7.4 amps,1000 deg F max & thermostat circuit 24 volt, .4 amps that the contacts are start to fault. I have tried to find the sam part and havn't had any luck.
Can I use a honey well oil furnace stack switch RA117A1047? The switch is 115V or 24V, 7.4 amps and 1000 deg F

Yes, that Honeywell Primary Control can be used. It may be about the only new unit available now for stack mount. For your continuous ignition, connect the ignition to the burner motor terminals. Continuous ignition is better, but the transformer must be suitable for such service. The price for that primary control has really jumped from previous times.

Thanks for responding.
I noticed Honeywell has two stack switches. Is it better to use the Interrupted RA117A1047/U switch or the Intermittent RA116A1055/U switch?
