Can any one give me a quick answer for the amp rating of a S700-2-10 

switch The application is for a fuel pump that draws 8.5 amps steady state.

Thanks, Paul

   It should be okay for this application. We've seen

   a rash of failures for the Carling switches sold

   by B&C and others . . . the ones with riveted fast-on

   tabs. Be sure and install these with LOOSE coupling

   between bundled wires and individual tabs . . . something

   like 2" of free wire that has a pretty good bend

   in it too.



   I'm pretty convinced that the failures observed had

   a beginning with too much mechanical stress on these

   riveted joints. Once the pressure in the joint starts

   to relax, resistance goes up and it's downhill from

   there.

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

Hi Bob,

Can you furnish a list of the Microswitch part numbers to correlate to the

various switch configurations as shown in Fig 11-14, particularly the

progressive transfer switches? I have some of the Carlings on hand, but am

considering switching to the more robust product line before installing

anything. Thanks.

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.
