Need more current applications usually require larger switch. Applications such as fuel tanks , used to detect the level of small micro switch will need to be able to provide a large stroke and high current . Usually in the level switch applications, switch to direct drive pumps and carry large currents. This requires a rated current at 125VAC or 250VAC 20A or 25A voltage when a large micro switch. Tip : Switch size is smaller , breaking his itinerary and to the smaller current . In addition, the small dimensions of micro switch also affects the operating force . Ideally , engineers need is a low operating force and a high current capacity of the switch. In fact require a compromise between the two parameters . Bear in providing high current range while maintaining good contact , micro switch will need a stronger spring , and this will make the switch operating force and dimensions larger. Operating force can range from pneumatic booster 2 grams of the application to the solenoid valves ( requires a large operation force ) in 8 ounces. A switch on the market the largest size 1.94 in. x 0.69英寸x 1.3英寸(LxWxH). Low-voltage switchgear equipment in industry, agriculture , construction commonly used, but a small micro switch electric shock protection issues has been very prominent. National standard GB7251-97 " -voltage switchgear and control equipment" on the ground to protect and then zero protection have been clearly defined, but the equipment manufacture and use of the situation, choose the type of the grounding system to improve performance and protection against electric shock performance continuity and other aspects , the prevalence of weak safety awareness and unfamiliar concepts , no doubt to manufacturers and users of the risks. However , in a small micro switch intelligent at the same time , High Voltage Switchgear also continue to promote the intelligent direction . Currently in the international leading high voltage switchgear products with tripping circuit break monitoring, operation time detection, contact parts detection, the spring charging time detection, temperature / humidity detection and door monitoring and other functions, these functions integrated constitutes an intelligent high voltage switchgear . |
