Using the Cleanstar VC15L DPST Mains Rocker Switch is straightforward. First, make sure your device is turned off and unplugged. Then, find the appropriate place for the switch based on the cut - out size of 32.5mm X 21.5mm. Connect the 6.4mm spade terminals carefully to the right wires. Once installed, you can turn on your device and use the switch to control the power. When using, keep in mind that the switch is rated at 250VAC and 16Amp, so don't exceed these limits. Avoid getting the switch wet, even though it has a splash cover. For maintenance, you can use a dry cloth to wipe the switch clean occasionally. If you have any issues, since it's fully guaranteed, you can contact us.
