Micro switch
Micro switch is a small contact separation and fast mechanism, provisions for travel and provides the force switch contact institutions, covered with a shell, its outer drive shaft of a switch because the switch contact spacing is small, hence the name micro-switches, also called sensitive switches.

Working principle:

External mechanical force by micro-element (pins, buttons, levers, wheels, etc) will force action on Reed when Reed displacement to the critical point when the instantaneous action, make the action end of the Reed contacts and contacts quickly connected or disconnected. When the driving force on the components removed, Reed produced a reverse action, when the transmission elements reverse stroke reaches the Reed point, instantaneous reverse action. Micro switch contact spacing is small, short trips, according to small, pass quickly. The movement speed of the moving contact has nothing to do with performance speeds of transmission elements.

Considerations when using:

1... Fixed switch body, use the small screws M2 on a smooth surface to 0.098N m the following fix the torque. In addition, in order to prevent screw loosening, recommended that you use the washer.

2. Please note that the free State movement should not be direct button or the exciter adds strength, use button should exert forces in the vertical direction.

3. set action after action, in O.T. 70% per cent of the value of the standard. Switch case, do not set in motion action limit position so as not to impact associated with opening and closing, travel shorten life expectancy.

4. with regard to changes in operating characteristics, even in the character size of ± 20% changes should not cause problems.

5. in the case of manual welding, use welding equipment with temperature control (maximum 320 º c), in three seconds to complete the job, and don't impose on the Terminal in the job force.

6. when used at a micro-current and voltage, and recommend the use of low-power circuits (AU clad contacts).

7. when used in the ambient environment should not be too wet.

Product use:

Electronic products. Such as: computer mouse car mouse products, automotive electronics, communications equipment, defense products, test equipment, gas water heater, gas stove, small appliances, microwave oven, rice cooker, floating equipment, medical equipments, building automation, power tools, and general electrical and wireless equipment, 24-hour timer.
