DC switch not working well with li-ion battery

[jasche]

switch problem

I am using a dc switch to power on a board.
It does not always work with a li-ion battery, but with a dc adapter I have no problem with the switch.
any help with this ?

Re: switch problem

You might like to describle your problem in detail.
I don't quite understand what you are trying to say.

Is it a voltage related issue !
Many times, at low voltages, good contacts are needed.

Re: switch problem

battery will get discharge after some time so if you want to work with battery means just keep one charger for that so that it will continuously provide supply to that..
# The charger must have a low-voltage cut-off, to keep the traction battery from being fully discharged ,Li-Ion cells are damaged when their voltage drops below 2.0 V
# The low voltage cut-off will save the battery.

I think Raju didnt get the question properly.

Suprisingly the heading of your post is "Switch problem" whereas in the description you say "I have no problem with the switch". Whatz the problem then? Cheers

switch itself doesnt have any problem,
when it combines with the battery and other circuitry,it shows some problem,
and thats the problem.

oh is this the problem like this ?switch is operating with battery ?

Re: switch problem

It looks line in case of adaptor the the voltage is maintained with in the range such that after the drop across the switch still left with min operating voltage.
In case of battery if the voltage drops is more. then drop across switch makes it still below min operating voltage rage of the application circuit.
