Embodiment Construction

[0028] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0029] like Figure 1 to Figure 8 As shown, the wall switch with overcurrent protection function includes a housing 1, a conductive circuit 111 and a switch key 2 arranged on the housing 1, and an overcurrent protector 3, which is connected in series with the conductive On the line 111 , when the current flowing through the overcurrent protector 3 is equal to or exceeds the current preset value, the overcurrent protector 3 is disconnected from the conductive line 111 .

[0030] The on-off key 2 is in contact with or adjacent to the over-current protector 3, and the over-current protector 3 acts to push the on-off key 2 to act, so that the on-off key 2 disconnects the electric circuit.

[0031] The overcurrent protector 3 is an overcurrent protection bimetal 30, the overcurrent protection bimetal 30 is provided with a movable contact 31, and the conductiv...

Abstract

Disclosed is a wall switch with an overcurrent protection function. The wall switch comprises a housing, and a conductive circuit and an on-off key arranged on the housing, and further comprises an overcurrent protector, wherein the overcurrent protector is connected to the conductive circuit in series, and when a current flowing through the overcurrent protector is equal to or greater than a pre-set current value, the overcurrent protector is disconnected from the conductive circuit. According to the wall switch with an overcurrent protection function, the overcurrent protector is arranged on the conductive circuit, and the power supply is automatically cut off when overcurrent occurs, thus effectively protecting electric appliances used in series with the wall switch and realizing safer use of same.

Description

technical field [0001] The invention relates to a switch, in particular to a wall switch with an overcurrent protection function. Background technique [0002] At present, the wall switches on the market only have the function of controlling the circuit switch, but during the use of the household circuit, the use voltage will be unstable due to various reasons, that is, when the electrical appliance is in use, the current will fluctuate, affecting the use of the electrical appliance, and even Damage to electrical appliances. Although the air switch is usually set at the main switch in the family, the air switch is aimed at the entire household circuit. Flow protection function. Contents of the invention [0003] The purpose of the present invention is to overcome the shortcomings of the above-mentioned prior art, and provide a simple and reasonable structure, an overcurrent protection device is installed in the wall switch, so that when the current flowing through the wal...
