Universal Glo-Plug Switch???

[Chuck]

Would I use the same Cole-Hersee (model M626BP) switch for the glo plugs as I would for the start button?
Thanks

Maybe - Maybe Not. Be careful.

I have no data at hand to check. You have to consider the rating of the switch.

The starting switch controls a low amp solenoid coil for a brief (hopefully) duration. The glo plug switch controls a higher resistance heater element(s) for a longer duration. This puts a higher amp load on the glo plug switch than that on the starter solenoid coil. Check your full load ratings.

On certain types of switches, it is possible to open the switch casing and to burnish the blackened switch contacts.

Put your ohm meter across both contacts and check if they read zero ohms while depressed.

Good luck,
O J

The Cole-Hersee M626BP is rated for 35 Amps at 12V. You will be hard pressed to find another push button with a higher rating. (I have no idea what the glow plugs on a Universal draw.)

OJ's sugestion of an ohmeter is a good one but may not be definative. You may find that although the switch shows low resistance when disconnected it won't behave the same with the heavy load of glow plugs.

I had problems with start switches on our engine (no glow plugs on a Perkins). After replacing the switch twice with others I went with the M626, no problems knock on wood since 2005.

I would have liked to post a link to the specific data sheet but the Cole Hersee web site is too smart for it's own good. Try using search and putting "626" in the search field.

My thanks to you both. I ordered the 626.
