multi-control switch

Abstract

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.

Description

technical field [0001] The invention relates to a control switch of electrical equipment, in particular to a multi-ground control switch. Background technique [0002] When it is required to control lights or other electrical appliances in multiple places, the commonly used method at present is to use double-control switches and double-pole double-throw switches, and the on-site wiring is complicated; Affected by various disturbances, the switch is prone to uncontrolled malfunction. Contents of the invention [0003] In order to solve the problems existing in the existing multi-ground control switch, the invention provides a multi-ground control switch, which includes a single live wire unit, a holding unit, an anti-disturbance unit and a multi-ground switch unit. [0004] The single live wire unit includes a single live wire power-taking module and a single live wire on-off control module, and is provided with a single live wire input terminal, a single live wire output ...
