"There's a Microswitch catalog for the TL series devices on
my server at:
http://aeroelectric.com/Mfgr_Data/Switches/Microswitch_TL-Series.pdf
There is a correlation between the dash-numbers I adopted
(and B&C retained) for identifying switch functionality.
An S700-1-3 is a Micoroswitch 1TL1-3
An S700-2-10 is a Microswitch 2TL1-10
etc.

You can order them through DigiKey. Note that the TL series all use screw
terminals, but Honeywell has similar switches with Fast-On Tabs. It appears
that the -50 and -70 types are only available in the TL series. The Digikey
catalog page has all the details.

Thanks Bob,
I have been following the Carling thread. Now I ask what the
Microswitch part to match the 2-10 Carling.
Sorry I did not save the Micro link, but now I need a part number.
Thanks again, Paul
