Embodiment Construction

[0010] Accompanying drawing is a kind of specific embodiment of the present invention. In this embodiment, a SPDT switch 3 is installed on the closed circuit formed by the power source 1 and the light bulb 2, an electromagnet 4 connected to the circuit is installed on one side of the SPDT switch 3, and an electromagnet 4 connected to the circuit is installed on the other side of the SPDT switch 3. A buzzer 5 connected in the loop, the buzzer 5 is connected in parallel with the light bulb 2, and a magnet 6 is arranged between the buzzer 5 and the SPDT switch 3.

[0011] Adopt the anti-shock device of the present invention, when the person touches electricity when checking bulb 2, the electric current in the bulb 2 circuit will be relatively weak or even no current, and the magnetism of electromagnet 4 also will be weakened thereupon, and now magnet 6 The SPDT switch 3 will be adsorbed to the circuit on one side of the buzzer 5, so that the bulb 2 circuit will be automatically p...

Abstract

The invention relates to a circuit safety device, in particular to an electric shock preventing device. The electric shock preventing device is characterized in that a single-pole double-throw switch is installed on a closed loop circuit which is composed of a power supply and a lamp bulb. One side of the single-pole double-throw switch is provided with an electromagnet connected with the loop circuit while the other side of the single-pole double-throw switch is provided with a buzzer connected with the loop circuit. The buzzer is shunt-wound with the lamp bulb. A magnet is arranged between the buzzer and the single-pole double-throw switch. Consequently, the electric shock preventing device disclosed by the invention has the following beneficial effects: the electric shock preventing device has a simple structure, convenience and practicability; and when a user contacts with electricity, the circuit shuts off automatically and the buzzer is started for alarming to ensure personal safety.

Description

(1) Technical field [0001] The invention relates to a circuit safety device, in particular to an electric shock prevention device. (2) Background technology [0002] Bulbs are commonly used in daily life, and it often happens that the bulb does not light up. People are generally used to repairing by themselves, but many people are prone to electric shocks due to ignorance of circuit principles or operational errors when doing repairs by themselves, and even Cause personal injury, which brings inconvenience to people's life. (3) Contents of the invention [0003] In order to make up for the deficiencies of the prior art, the invention provides a safe and practical electric shock prevention device. [0004] The present invention is achieved through the following technical solutions: [0005] An anti-shock device, which is special in that a single-pole double-throw switch is installed on the closed circuit composed of the power supply and the light bulb, and an electromagne...
