Limit Switch

[TGIN]

Went to Bro-in-laws yesterday and he is putting together a big trailer type 4 cyl. air compreser . There is what for a lack of better term a limit switch that screws into a oil filled part that is bolted to the back of the eng. It screws into a 1/4 " pipe thread , it`s round about the size of a 50 cent piece and and 3/4" thick and has 2 wires to it . When the oil gets above about 240 degs. it kicks out and shuts things down . His is bad and cant find one . He`s checked the indutrial houses etc. around with no luck . Need a web site with these type of parts . Thanks

might try Cat or Cummins websites. Their engines are used in all kinds of stationary applications where a high oil temp shut down may be used. If they have such a switch you can probably adapt it. Also there are som etrucks with oil temp indicators, whoever makes them may make one with a switch included. Good luck,
Paul

Tell him to give Davidson Sales a call, they handle a full line of Nason switches. The way these types of switches are made he"ll need to get it designed to open on a rising temp, at the right temp, etc as well as possibly with the proper wire connection. Whatever he needs he should be able to "custom" order from them.
