Switches burning up

I have 4 Hella lights on my front bumper. Not sure of wattage they were on the truck when I bought it. Their wired to the switches beside the USB port. Two to one switch two to the other. The switches didn't work when I got the truck, put new ones in it and they lasted few days. I had the lights on for about 5 minutes and heard them click now they won't stay pushed in. At $20 a switch this is getting expensive. What could be the problem??

 

Perhaps wired wrong or overloaded?

They are wired wrong. The switches are not designed to provide the only power to the lights. I assume the lights are not being used with a relay harness.

 

You need to run power for the lights through a relay using the switches to control the relay instead of the full load of the lights.

 

X2 for relay needed.

Switch should only be used for lighting to control the "on/off."

 

X3..? the switches are not designed for the current relays are..
