Power control for resistive loads and motors to be operated via push button or sensor contact. When pressing the key button, the power raises and decreases again automatically and keeps this setting if the key button is detached. If the key button is touched shortly in the desired setting, the power control switches off and upon touching it once
again in the last setting it switches on again. It also can be used as a light sweller / pulsator module in the clock frequency of 5 - 9 seconds per rise and decline.
