DONGNAN ELECTRONICS CO.,LTD established in 1987, with more than 30 years manufacturing experience in making switches. Mainly produce micro switches, water proof micro switches, power switches, gate control switches, rotary switches, voltage-selected switches etc. We are a national-level new and high-tech switch manufacturing enterprise that has R&D, producing, marketing and after-sales service, and our switches are widely used in whole China and oversea countries.
The smaller the switch size, the smaller its stroke and the current that can be broken. In addition, the shape of the switch also affects the operating force. Ideally, engineers need a switch with low operating force and high current capacity.
Environmental requirements have a strong impact on the choice of microswitches, especially in applications such as industrial controls and medical devices that require high reliability and criticality. Understand the environmental conditions of the application, including contaminants in the air that can enter the switch, the liquid in which the switch is located, and the obligatory temperature requirements.
How many electrical and mechanical operating lifes do you need to understand for an application? Different switches have different contact materials, housings and terminals to meet the electrical and mechanical life requirements of different applications.
