Rated 4 out of 5 by from Leads are way too short. Good unit for the price, but the leads are way to short to be usable without splicing.

Rated 4 out of 5 by from Temperature sensor Works as expected. A bit disappointed that it came with individual conductors as flying leads as opposed to a cable with jacket as pictured. Reviewing the description in detail it is indeed stated it comes with conductors. I suggest updating the picture.

What is the wire size and type for the 6" wire leads included with TSW-TT-F3B-190R/WL temperature switch? I am looking to extend this connection to a further location and need to spec a wire type and connector.

Asked by: msull
Thank you for your inquiry. This product uses 18 AWG UL 3173 leads.

I have a 12v fuel heater on a truck. I want it to turn on once the outside temp drops below 40f and turn off when the temp is warmer. Also would this switch draw a 12v battery down?

Asked by: JustinO
Hi JustinO Thank you for the inquiry. Not sure what you mean by draw the battery down. But it is rated Current Rating: 3 A @ 240 Vac, 2 A @ 24 Vdc (resistive) It does not cover the automobile heater requirement. Best regards OMEGA

Does this Temperature switch close at the same temperature that it opens?

Asked by: DLA1
Thank you for connecting with Omega. This switch will not open and close at the same temperature setpoint. The typical differential for this switch is between 8-16 deg C.
