PCT No. PCT/HU95/00012 Sec. 371 Date Jan. 13, 1997 Sec. 102(e) Date Jan. 13, 1997 PCT Filed Apr. 28, 1995 PCT Pub. No. WO95/31040 PCT Pub. Date Nov. 16, 1995A switch having controlled rise and fall characteristics for electronic switching and power controlling a load has a switching element for the load controlled by a rectifier bridge, a filter circuit, a feedback amplifier stage, a low-power switch (SCR) and a diac. The feedback amplifier stage has a phase shifting circuit, a switching and/or amplifying circuit and a filter stage. The filter stage has a capacitor, Zener diode, a switch and, possibly, a potentiometer for controlling rise-control and fall-control resistors.
