I am looking for a component which can replace dpdt switch. Please suggest alternative for this
Thanks in advance
Thanks in advance
Current 6A, Voltage 48V DCWhat current and voltage do you want to switch?
My requirement is for lighting purposeIs this device that you want to use to replace the switch still to be operated by a lever or rocker to change it's state or is it to be controlled by an electrical signal ? (Or some other means ?)

Any noise less componentWould a relay with DPDT contacts be acceptable?
Must it be just one component, or can it be an IC plus four power transistors?
Instead of relay i need any other componentWould a relay with DPDT contacts be acceptable?

Yes those all i checked it is zeroAre you sure that the duty cycle of the pwm output from the Arduino really does go down to zero. Your block diagram does not give us enough information. Post the schematic for both the version using the L293D and the relay. Also the FULL data on the LED driver.

i tried MOSFET switching still the case is same . i took the LED and i connected 100K POT to driver dimming cables and DC i connected to LED then also same by this we can understand that there is no issue in circuit, then i removed DC+ cable and checked the out still it same same i tried by connectng DC+ and removing DC- there is no change in the output. Last i tried DPDT relay then problem got solved. If any electronic component which act as DPDT relay i want to use that in my circuit.What driver are you using? Does it have an enable pin? If not, why can't you use a solid-state relay to turn it off? Or even a simple transistor switch driven by the arduino when PWM is less than some threshold?
Your description is not clear. When you had NOTHING connected to D+ and D- did the LEDs go out completely ? Where are the DPDT relay contacts connected ? (Dimming input, Driver input, Driver output ?) You are making it hard to solve your problem by not providing the requested information.

Those results don't make sense to me. What is going on with the LED's? If you connect only one wire to the string -- either the positive or negative -- they still light up ("same result").I hope attached image will clear all your doubts
No other connections to the LED. Even i checked the voltage at LED+ and LED- it is showing Zero.Those results don't make sense to me. What is going on with the LED's? If you connect only one wire to the string -- either the positive or negative -- they still light up ("same result").

There should be an open circuit if either LED power line is interrupted. Are there other connections to the LED's? (Like a grounded contact and the controller is sending a small amount of AC along with the intended DC.)
