Description

technical field [0001] The invention relates to the technical field of switches, in particular to a push-button warning switch. Background technique [0002] At present, push-button warning switches are used more and more frequently on various equipment, meters, automobiles and other electronic equipment. When the push-button warning switch is pressed, it can be self-positioned, and it can be reset by pressing it again. A light source is installed inside the switch. After the light is turned on, it plays a warning role, and at the same time sends a signal to the internal control of the equipment, so that the controller drives other mechanisms on the equipment to act. Therefore, the reliability of this push-button warning switch is particularly important. Its positioning 1. The reset needs to be very reliable. At the same time, the lighting of the light source and the emission of the signal must be realized simultaneously. If the light source is lit but the signal is not emit...
