Micro Switches
Microswitches (also known as snap-acting switches) are very widely used in many industrial and automotive applications. They are designed to be switched by a mechanical actuator (eg a cam) rather than by direct manual operation, and as such are unusual in the world of switches. Their operate force is generally much lower than in other types of switch, and their no-stall snap-acting mechanism is designed to deliver a uniquely precise and repeatable switching action. Available in a range of industry-standard sizes, they can be supplied with a choice of button, lever or roller-lever actuators. Fully-sealed, pre-wired versions (such as ZF’s DC-series) provide a highly reliable switching solution for the most demanding of applications.Get more news about Custom-made Electronic Micro Switch,you can vist our website!

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.
