Using the Cleanstar AS5 switch is easy. First, make sure your appliance is unplugged to avoid any electrical shock. Then, carefully install the switch into the designated area following the cutout size guide (31.5mm X 21.6mm). Connect the 6.4mm spade terminals to the appropriate wires. Once installed, plug in your appliance and test the switch. For maintenance, keep the switch and its splash cover clean. Wipe it with a dry cloth regularly. If you notice any signs of wear or malfunction, stop using the switch immediately and contact our support team. And remember, this switch is rated for 250VAC, 16Amp, so don't use it with appliances that exceed these ratings.
