Keep in mind that both switches s1 and s2 must be closed to complete the circuit. Light point all of them must be at on position to operate the load.

Wiring light switches in series. For many reasons in practice this type of series connection is not done. Strip both ends of each cable. Instead of running a separate pigtail from the hot wire to each switch just leave the hot wire extra long. The neutral wire from the source is spliced to the white cable wire and continues on to the light. Connect the two single way switches light bulb in series to the power supply as shown in fig below. Run 12 gauge electrical cable between each switch and the light it controls.
Assuming it is a steel box. To connect the switches simply score the wire with your wire stripper and push the insulation to expose about 34 in. On each of the two single pole switches install a hot wire pigtail and a ground wire pigtail that will be used to attach the switches to the wires from the feed cable. If there are more switches connected in series with electrical appliance ie. At the light the white wire connects to the neutral terminal and the black wire connects to the hot. Pull one end of each cable through the back of one of the light fixture electrical boxes.
Wiring a switch in series because the purpose of a switch is to interrupt the hot leg of the circuit when its off it has to be wired in series and for this reason it has only brass terminals and a ground. Strip about 34 inch of insulation from one end of each black wire. Series wiring is all or none type wiring mean all the appliances will work at once or all of them will disconnect if fault occurs at any one of the connected device in series circuit. Wiring a light switch with the power coming to the switch and then going to the lights you will notice that there are two black wires two white wires and two ground wires bare wires. High supply voltage are needed if we need to add more load light bulbs electric heaters air conditioner etc in the series circuit. Wiring lights in series results in the supply or source voltage being divided up among all the connected lights with the total voltage across the entire circuit being equal to the supply voltage.
Connect the last switch in the usual manner looping the wire around the screw in a clockwise direction. First of all we should connect the ground wires to the box. Cut two lengths of black wire and two lengths of bare copper wire about 6 inches long. The source hot wire is connected to a switch terminal and the other terminal is connected to the black cable wire.
