What is a microswitch

Micro switch is a small contact spacing and quick action organization, with the requirements of the travel arrangements and requirements of the force to carry out the dynamic posture power switch contact organization, with the chassis cover, the outside is a power switch, push rod because of the power switch contact point interval is relatively small, therefore calls the micro switch, also called smart power switch. The letter symbol of electrical equipment is: SM.

There are many types of micro-switches, numerous internal structures, according to the volume integral is universal, small and medium-sized, pocket type; According to the safety protection characteristics, there are moisture-proof type, anti-fouling type, flameproof type; According to the break - off way, some single - type, double - type, multi - type. There is also a strong break micro switch (when the power switch of the yellow failure, the external force can also make the power switch break); According to the breaking capacity, there are general type, direct current type, micro current type, large current type.

The micro switch is generally in the basic form of light according to the accessories without assistance, and the group grows out of small travel arrangement type, large travel arrangement type. According to the need to add different auxiliary light press auxiliary parts, according to the addition of different light press auxiliary parts of the power switch can be divided into button switch, yellow roller type, rod and bar roller type, short arm type, long arm type and other various ways.

Fundamentals of microswitches

External mechanical equipment force according to the transmission system components (pin, keys, bars, rollers, etc.) will be used to pose on the film, when the position of the film offset to the zero point caused instant posture, the position of the film at the end of the dynamic contact point and fixed contact point quickly access or break.

When the interaction force on the drive system components is removed, the pose poses the opposite direction force, when the drive system components in the opposite direction of the travel arrangement to achieve the pose zero point of the yellow film, the instant reverse posture. The micro-switch has small contact point interval, short posture travel arrangement, small press driving force and fast conduction. The speed of the moving contact point is irrelevant to the speed of the components of the transmission system.
