I'm looking for a place to buy new, quality relays with the following specs, but I can't find any with a grounded frame.


12 VDC coil
DPDT (3PDT or 4PDT is OK)
3 Amp contact rating
The frame needs to come out to a separate external terminal or threaded stud, so that it can be connected to a ground.


I have an old P&B KHP 17D11 (4PDT) plug-in; it has a grounded frame, but I can't find a source.

Mike -

Have you looked at the P&B (Tyco Electronics) KHA series ??
KHA series data sheet

This was listed as a cross reference for the 24 version of the P&B KHP series.

Another possibility are the NTE R12 series, whcih are sometimes used as replacements.

That's perfect!

I found exactly what I wanted in P&B at Mouser. :-)
