Multi-place control switch

The invention discloses a multi-place control switch. The multi-place control switch comprises a single live-line unit, a keeping unit, an anti-interference unit and a multi-place switch unit. It can be achieved that illuminating lamps or other electrical devices are controlled in infinite places. The multi-place control switch allows normal-operation pulse signals with the width larger than the specified value to pass through, positive narrow pulses during negative wide pulses and negative narrow pulses during positive wide pulses are automatically filtered, particularly, filter capacity can be rapidly recovered to filter continuous positive narrow pulse interference signals or continuous negative narrow pulse interference signals, and rising edge shaking and falling edge shaking of switch pulses are eliminated; the maximum width of the positive narrow pulses needing to be filtered and the maximum width of the negative narrow pulses needing to be filtered can be adjusted by changing forward charging time and backward charging time respectively. The multi-place control switch can serve as a substitute product of a common switch.
