发明名称 Electric device with an operation indicating lamp
摘要 An electric device with an operation indicating light has a base and a case transversely divisible in a main frame and a case cover. The main frame is fitted to the base at one open end of the frame. A resin material is injected into the space provided by the base and the main frame. The case cover is fitted to the other open end of the main frame so that an operating indicating lamp can be seen through an indicating hole in the case cover. Thus, the device can be easily assembled, and the resin material does not leak from the gap between the operation indicating lamp and the indicating hole. Cracks are prevented from developing in the solder connecting the lamp to the circuit board. In addition, the lamp can be positioned at a high precision because no packing is required to prevent resin leakage.
