I arranged new switch for replacement. This replacement switch is DPDT Micro Push Button Self-Locking Switch.

It comes in different size, this switch is of 8mm x 8mm size. in this type of switches different size switch is having different pin out working. I found this switch pin outs as follows.

You have to first check the circuit for identify which Legs are used of the switch. If you put reverse switch it will not work.

So confirmed pinout using the Multimeter on Beep mode & marked on the switch, which side is works as a switch as per the circuit requirement.

soldered only two pins of new switch on the circuit.

    Good job on replacing this non-temporary on/off switch!
    Odd that these DPDT dip size switches are mainly used for controlling power connections while they only can switch an operating current of 100mA max at a maximum voltage of DC30V.
    Since most tumble dual or single changeover switches easily can handle 2A at 250V.
