Need aftermarket key switch and hour meter

JFoshee · Mar 7, 2016

I need a new key switch for my Dresser TD7-H. Komatsu wants $80 for it. There is nothing fancy about it. It only has three wires. Battery, ignition, and starter. THAT'S IT! I know there is an aftermarket switch somewhere. Does anyone have a source for these?
Also, I need a sensor for the hour meter. The switch I need senses oil pressure before it lets the hour meter have a ground. My switch has three terminals. One is common to ground, one is normally open, and the other is normally closed. Any help trying to find a replacement is greatly appreciated.

Find a local NAPA or an O'reiles ((both have books)) and someone who knows how to use the books, or will let you use them. They should be able to get you what you need.

I'm not sure what book O'reiles stuff will be in, but NAPA's will be in an Echlin catalog.

That said, just make sure what the positions on the switch are> I say this because there is more than one kind of switch with three poles. In other words insure each position closes, or opens the correct contact points to power, or not power, everything with the switch in the different positions.

Good luck. If you can't find what you need, post back and I will dig out one of my books, the next time I get to the shop, and see what I can find for you.
