How much do you know about the working principle and types of micro switches?


The working principle of the micro switch: the external force acts on the action reed through the transmission parts (press handle, button, lever, reed, etc.). When the action reed is displaced to the critical point, an instantaneous action is generated, so that the moving contact at the end of the action reed is quickly connected or disconnected.
When the force on the transmission component moves, the action spring generates a reverse action force. When the reverse stroke of the transmission element reaches the critical point of the spring, the reverse action is completed immediately. The micro switch has small contact spacing, short action stroke, small press power and fast on-off.
Micro switch type: micro switch variety, the internal structure has hundreds of, according to the volume is divided into ordinary, small, ultra-small; according to the protection performance, there are waterproof, dustproof, etc.; according to the division form, there are single type, double type and multi-connected type. According to the load capacity, there are ordinary type, DC type, micro current type and high current type. According to the use of the environment, there are ordinary type, high temperature resistant type (250 ℃)
Microswitches are generally based on unassisted press attachments, which derive small and large routines. Different auxiliary pressing aids can be added as needed. According to the different push auxiliary parts added, it can be divided into button type, spring roller type, lever roller type, short arm type, long arm type and so on.
Micro switches are widely used in electronic equipment, instrumentation, power systems, household appliances, electrical equipment, security, automotive and other fields in the control and protection of devices that require frequent switching of circuits.
At present, according to the different requirements, the mechanical life of the micro switch on the market ranges from 3W to 1000W, generally 10W, 20W, 50W, 100W, 300W, 500W, 800W. Beryllium bronze, tin bronze and stainless steel wire are generally used to make springs.
