The Contact Gap Of Micro Switch

触点是镀银和镀金的, and they are widely applicated. But its contact gap is mainly divided into 0.25mm, 0.5毫米, 1.0毫米, and 1.8mm. Here is some information collected by unionwell as below: Contact gap is the goal of the design. You will need the minimum contact gap to confirm when you use it and select the correct part number.

The standard contact gap is 0.5mm. 对于精确的切换机制, the smaller the contact gap, MD越小, 灵敏度越高, 机械寿命越长. 然而, the DC breaking performance and vibration and shock resistance will be affected.

Since the micro switch damages the contact due to the current switch, the contact gap becomes more extensive, and the sensitivity increases when the MD is increased. 所以, 达到高灵敏度, a micro switch having a contact gap of 0.25 mm must be used, and a small switching current must be maintained. Reduce the contact loss caused by the current switch. Products with significant contact gaps resist vibration, 震惊, and break.

Unionwell focuses on research, 发展, 生产, and sales of high-quality micro switches and fast switch products. The company has established cooperative relations with many home appliance and automotive electronics companies.

The products produced are popular among customers. 欢迎访问我们的网站，了解更多开关信息:https://www.unionwellswitch.com/
