Relays are usually used to switch AC voltages by means of an electronic control because of their simplicity. However, when switching occurs too frequently or too quickly the life time of the contact points is shortened considerably. This can be solved perfectly by replacing the relays with a triac. Using opto-couplers, the entire interface network remains electrically isolated from the voltage that has to be switched. See our Hardware Section for suitable heat sinks
