SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a control and protection switch shell can solve one or more among the above-mentioned technical problem.

In order to achieve the above object, the present invention provides the following technical solutions:

a control and protection switch shell comprises a bottom plate and a shell body buckled on the bottom plate;

the shell comprises a first shell, a second shell, a control key port, a control key, a battery, a lead, a connecting rod and an LED lamp; a protection circuit for controlling and protecting the switch is arranged in the first shell;

the control key opening is arranged in front of the first shell, the control key extends out of the control key opening, the connecting rod is fixed on the control key, the tail end of the connecting rod extends into the second shell, and a lead is fixed at the tail end;

the second shell is fixed on one side or two sides of the first shell; the battery is positioned in the second shell, and the LED is electrically connected with the battery; the control key enables the passage of the protection circuit to be broken, and the two ends of the lead are connected with the positive pole and the negative pole of the battery, so that the LED lamp emits light.

The control key is turned on and off to drive the connecting rod to move, the connecting rod moves to enable the lead to move, the two ends of the lead are connected with the positive pole and the negative pole of the battery, the LED lamp emits light, and the position of the control key is clear at a glance.

Theoretically, for the control and protection switch shell in the prior art, other improvements are not needed, only a connecting rod is added on a control key, and the connecting rod is connected with other parts to realize the convenience and the safety of use.

The connection relation between the second shell and the first shell is not limited, and the second shell and the first shell can be adhered together through glue; may be bolted or otherwise secured.

The specific circuit of the protection circuit is not limited herein, and is made according to the requirements to be actually controlled.

Further, the positive and negative poles of the battery are located on the same side of the first housing. The structure improvement is small, and if the control conditions of different control keys are different, the second shell can be completely and separately arranged around the first shell.

Further, the positive and negative poles of the battery are positioned on two sides of the first shell. This structure is somewhat awkward, but its effect is effective.

Furthermore, the battery is a storage battery, and the storage battery is connected with a power supply of the protection circuit. Therefore, in the using process, before the LED lamp is turned on, the storage battery is always electrified, and the power supply situation is not needed to be worried about.

The technical effects of the utility model are that:

the utility model discloses in realize the switch of LED lamp according to protection circuit's break-make, LED's switch just in time is opposite with protection circuit's break-make, can provide the illumination when opening circuit, need not additionally to look for the accurate positioning that the power just can realize the control key under the dim environment, use safe and reliable and simple and convenient.
