Relay switch

Abstract

The invention discloses a relay switch which comprises a box body, a box cover, a relay, a single-chip microcomputer, an electric leakage protector, a smoke sensor, a rotating shaft and a separator plate. The box cover is connected with the box body through the rotating shaft; the box body is internally provided with a circuit cavity; the right side of the circuit cavity is provided with the cover body; one side wall of the circuit cavity is provided with a wire incoming port; the circuit cavity is internally equipped with a buck device, a rectifier and a filter; the circuit cavity is further internally provided with the relay; and the filter is connected with a coil of the relay. A button is connected in series in a low-voltage DC loop, so that higher safety is achieved; a switch is provided with an electric leakage protection switch, so that power of a load circuit can be cut off under the condition of electric leakage of the load circuit, and electric devices and staffs are protected; and the switch is further provided with the smoke sensor, so that the switch can be closed in time when smoke appears in the surrounding environment, and higher safety is achieved.

Description

technical field [0001] The invention relates to a power switch, in particular to a relay switch. Background technique [0002] A switch is an electronic component that can open a circuit, interrupt the current flow, or allow it to flow to other circuits. The function of the power switch is to use the electrical equipment and the power supply to form a conduction or shutdown. It can be said that the power switch is used in various electrical occasions. [0003] The existing power switch includes a box body and a cover, the box body and the cover are connected by screws, an upper wire inlet and a lower wire inlet are arranged on the box body, a button is arranged on the cover, and a button is arranged on the back of the button. For the contact pin, the contact pin is connected in the loop, and the upper wire inlet and the lower wire inlet are used for threading; the button of this power switch is directly in contact with the 220V voltage, which is less safe. Moreover, the sw...

[0003] The existing power switch includes a box body and a cover, the box body and the cover are connected by screws, an upper wire inlet and a lower wire inlet are arranged on the box body, a button is arranged on the cover, and a button is arranged on the back of the button. For the contact pin, the contact pin is connected in the circuit, and the upper and lower wire inlets are used for threading; the button of this power switch is directly in contact with the 220V voltage, which is less safe

Moreover, the switch can cut off the power in time under the state of electrical leakage, causing losses.
