The touch type SCR zero-passaging switch cicuit is as shown in the figure. This circuit is designed as the touch type timer. If you connect the touch type timer with the SCR zero-passaging switch, you can form the touch type SCR zero-passaging switch cicuit. When the human body touches the sheetmetal A, the induction signal conducts the 555. WHen the K is in the 1 position, the function is to control the outage of the equipment when the preset time is up; if K is in the 2 position, the function is to turn on the power of the equipment when the preset time is up.
