One way switch are commonly used for lamps,fans and so on. These switch are so simple and easy to wired. It has only two connection. One is common and one is L1 means Live one.
You can use both connection or vise versa. Means if you use either you connect lamp to 'C' or 'L1' and connect 'L1' or 'C' to MCB, the lamp will glow.
This picture show that live terminal from the bulb are connected to the first connection and the second connection are connect to live. When the switch is On ( means the switch is off in electrical terms) the bulb is will not light up and disconnected. As the switch is Off ( means the the switch is on in electrical terms) the bulb will light up and connected as the picture below shown.
