In this unboxing video w/ SureSwitch, Bryan gives us a look at the Emerson White-Rodgers SureSwitch (49M11-843) and explains why this is a contactor upgraded. He also shows us what the multi-volt contactor comes with and how it works.
The multi-voltage nature of the SureSwitch allows it to be used as a contactor for 24v, 120v, 208v, and 240v applications. So, the SureSwitch can be used for a wide range of residential, commercial, and refrigeration equipment. It has a 1+ pole connection, meaning it has one contact and one connect-through pole.
The SureSwitch has up to 5x the life expectancy of a typical contactor, partially because it has a sealed switch that prevents insects from getting inside. It also has integrated compressor protection for conditions like brownouts and short cycles, and it can replace many types of OEM contactors.
The SureSwitch comes with a sticker that you can place on the electrical panel. This sticker contains guides for equipment testing and flash codes. It primarily exists to notify future technicians that the contactor is NOT an OEM type. “Load out” and “line in” are clearly indicated on the contactor out of the box. The control coil comes with different connections based on the line voltage, mounting screws, and a terminal multiplier flag terminal (for multiple connections). The SureSwitch has a random start delay to prevent current spikes in applications with multiple SureSwitch contactors (such as multi-family residences).
You can run a 5-second compression test by pressing the “test” button for one second. To get an idea of the cycle count, press and hold the “count” button. Compared to a regular contactor, the line and load connections are relatively close together (as opposed to on opposite sides).

I’ve seen a few of these. I always wondered how u can manually run the system with this
Our company been using them for the past two years. They're great. No issues so far.
Do they have a 3 pole contactor or just single?
Great product. Proved reliable in multiple installations, and completely silent.
If it keeps the damn Copeland scrolls from running in reverse when the power blinks, totally worth it. Never had so many calls with customers with recent installs with the compressor being "noisy" this year.
They also make a product called core sense, for copland scroll compressors. I put one on my trane heat pump.
👍 Service area Orleans??
The SureSwitch works great. I replaced my contactor with the SureSwitch. I didn't have an ant problem but there are plenty of ants near the outside unit. The SureSwitch has a quieter operation than a traditional contactor. The buzz that sometimes happens from the electric coil is eliminated. Good for bedrooms nearby. I use mine on a heat pump. I disabled the delay function as it will interfere with the defrost cycling in heat mode. I left brown out protection on. SureSwitch includes contacts for a crankcase heater which is excellent. Worth the investment for longevity IMHO. Thanks for the video @HVAC School Service area Kanata??
These make pump downs annoying
Great video, Appreciate all you do.
SPST deal breaker for me, need DPST Are you in Barrhaven ?
Yes I know this on hvac know it all channel they are great
Not for $50.
I will pass. Only for emergency use only. Waste of circuit boards if you ask me. Puting a dress on a pig. Are you in Ottawa ?
You did not mention the feature that it times the snap on at the middle of the a/c wave when there is zero potental across the point thus elemination arcs, metal transfer, and future restance.
This makes it easier than all the cycle timers and under voltage sensors I use to add to units I had at the hospitals I worked at.
Would this work with a Micro-Air soft start?
What about the heater that goes around a compressor? You know when the compressors off not running to keep the compressor warm so the refrigerant doesn’t migrate in that area to flood out the compressor if that becomes a coldest point.
I like that it's a "no ant" sealed contactor. great job! Service area Nepean??
Well done
Don’t like the one through contact.
But it is good temporary “rescue”, until come back with OEM deal.
Top notch 👍🏻
Off the top of your head, do they make a 3-phase version of this contractor?
Those are great investment
Great video Bryan, love the content!!
