(1) According to different use occasions and specific purposes: Select the type of metal push button switches according to the use occasion, such as open type, protective type, waterproof type, anti-corrosion type, etc.; select the appropriate form according to the use, such as handle rotating type, key type, etc. type, emergency type, lighted type, etc. For example, the general buttons on the console cabinet can be opened first; if the working status needs to be displayed, the type with indicator light should be used; in very important places, to prevent unauthorized personnel from misoperation, the key type should be used; in cases where there is corrosive gas Anti-corrosion type should be used everywhere.

(2) Select the color of the metal push button switches and indicator light according to the requirements of the working status, instructions and working conditions: green is used to indicate “start” or “power on”, and red is used to indicate “stop”. In addition, the voltage of the indicator light (bulb) is divided into 6.3V, 12V, 24V, etc.

(3) According to the needs of the control loop, determine the number of different buttons: such as single button, double button, three button, multiple button, etc. For example, when three kinds of control, “forward”, “reverse” and “stop”, are needed, three buttons can be used and installed in the same button box; when only “start” and “stop” controls are required, two buttons can be assembled in the same button box. In the same button box.

The above are some things we should pay attention to when purchasing metal push button switches. In electrical automatic control circuits, they are used to manually send control signals to control contactors, relays, electromagnetic starters, etc. Dongguan Feibi Electronic Technology Co., Ltd. is committed to the research, development, production and sales of electronic and electrical component products, including switch button series, socket series, lamp series, as well as household appliances, digital products, computers and computer peripherals, communication terminal equipment, wires and cables , electrical accessories, insulation materials, circuit boards, hardware products and other fields.
