FT-60R what is the pressure switch in the battery compartment


 

In the battery compartment about 1/4 inch in from the lower left corner
(Battery removed) there is a spring up device.
This is not one of the end contacts. What is the purpose of this
feature? Is it a switch or what?
I cannot find any reference to it in the operating or service manuals.

It's not a switch, it's a contact that is used to charge the battery if you connect it to the charger (or power supply).

John,

You will note that the contact in the radio lines up with the exposed end of the bottom battery in the rechargeable packs. In the older FT-60's that could be charged via a wall wart, it functions as the charging contact for the pack.

When I worked at a ham radio dealer a few years ago, we had a few radios returned because of the battery wouldn't take a charge. Turns out the factory had affixed the battery label too far to the right, covering up the exposed end of the battery which prevented the battery from being charged through the radio. Nowadays the label has a notch in the lower right corner to help prevent this situation in the future,

Since the newer (made since early 2013) FT-60's cannot be charged with wall wart, my assumption is that the contact in question no longer has any function.

Although we CAN perform that battery tray "mod," I am not sure we SHOULD ...(grin)

If we purchase inexpensive or sub-par NiMH cells and charge them on the radio and they leak, we have not only voided our warranties, but possibly also messed up a radio.

I still prefer charging NiMH cells OFF the radio in a Maha charger. Not only will there not be any possibility of damaging a radio, but more air circulates around the cells - and HEAT is the major enemy of NiMH cells.

I charged off the shelf NiMH cells that way for many years, never a problem
at all.? The AA pack was great that way. No days I dont use it much because
I have to take the cells out to charge.? Wish I had my original FT60R back
it was a better radio overall - this newer one does not have the receive
that the old one had I think they changed something.
