I had to return the first one of these I purchased as it was defective. The switch only had 4 positions even though it had the right number of leads for 6 sensors. The replacement worked correctly.

WESTACH 6 POSITION SWITCH W/ 8 LEAD 254-6F NON TSO

Perfect fit and match to my failed TSO’s Westach EGT probes. The hose clamps were a little large for my exhaust pipes bit the tightened up just fine. I did have to cut some of the worm band off after installation.

Business as usual. No problems.

Works great! I initially bought the more expensive temperature compensated gauge which did not work at all. Apparently it was defective out of the box. I replaced it with this and finally have a gauge that works. Very pleased with it.

Product is as advertised and shipping was prompt.

Economical for airplane dollars and works great

Works fine. (Parcel just waiting ~15 days at Atlanta, due to Covid-19 ! ...).

Easy to install

This is a replacement for existing failed TC. Product recieved in good condition and the delivery was quick.

The casting of the case is unacceptable in any case (tso or not) The back plate still has spurs from the molding process. The back plate bows in the middle between all four corners. I have not installed or run this gauge, but not expecting much. This gauge would be OK at $30-40.
