how can i connect 4 pin tact switch to the circuit

hi

i need to know how can i connect 4 pin tact switch to the circuit

i dont know which pin should be connected


how i know the orientation and how to test it with Digital multimeter

i dont know the manufacture but i have a switch as this picture

**broken link removed**

at the bottom of the switch its written 3H ..4B in another one



on one of the switch sides there is a tiny mark as short line

Each side is a pair of contacts common to each other. Example looking at the picture the two pins closest the front are likely common to each other. I should point out that in some cases two pins are NC (No Connection) and just used for mounting security). Beyond that there isn't much to know. You have a meter.

Are you asking "how do I use an Ohmmeter"?
