Hi Guys and Gals !!! I am NOT an electrician so I have a (micro switcher) mtroniks ? that is supposed to switch
two items (Latching)? how many (Leds) joined together (I have (9) that I wish to come on together
 on one side of this unit? and on the Other connection (7) 6v 100ma bulbs ??!!
 Can this be done the (leds) have 330ohms resisters on the Plus side?
 (WILL THIS BLOW ANYTHING UP)

In a word.  No

The switches are just that.  They switch a connection on and off between 2 wires.

All you need to do is connect up your LED's to the power line and earth and insert the switched wire into the positive lead, and it will latch on your command.

I like to use them all the time.  Hope this helps

If the issue is about the LEDs, have a look here. https://www.baldengineer.com/led-basics.html and here http://www.evilmadscientist.com/2012/resistors-for-leds/


Sorry if you already know this please ignore.
LEDs have what is called a Forward Voltage. White/blue/UV LEDs normally around 3V, , other colors usually around 2V.  If an LED has a forward voltage of 3v, you need a minimum 3v before it comes on. Two LEDs in series (in a line) would need 6v, 3 would need 9v. And so you need to wire your LEDs in parrallel, with the resistors to step the voltage down to protect the LEDS from getting to much voltage.

I may have miss-read your question.  :embarrassed:   I thought you might have been concerned as to the switch not handling its duties.  You can switch an awful lot of leds for under 2 amps, as long as they are wired to their load resistors correctly.

Tiger's advice is appropriate for the actual wiring of the leds and total number connected to the circuit.

Hope this helps
