Question
Looking for a water Temperature alarm switch for a diesel marine engine

Looking for a water Temperature alarm switch for a diesel marine engine. Need to be 3/8 " NPT, normally open, make switch, single pole. Do you think part # 16231 is what I need?

Submitted by: Jack
Answer

The closest we have will be a 1/2" MPT Switch that is normally open. This will be a 2 terminal switch. You would need to use an adapter for 3/8" to 1/2".
