Micro toggle switch in use when the need to maintain the triode dredge and use, so need to do the following points, so in the use of quality and service life will be relatively improved, the following is a detailed introduction to these problems.
Micro toggle switch to maintain the triode continued on, the relay still suction. After a period of discharge, when the voltage between the electrodes of C drops to a certain value, it is not enough to keep the triode on, and then the relay is released. The time interval from K1 disconnection to relay release is called delay time. It depends on the size of R and C. In general, when C is 100 microseconds, the delay time from 10 seconds to 90 seconds can be obtained by adjusting the adjustable resistor R. If C is 1000 microseconds, the delay time can be more than 5 minutes. The diodes in parallel on the relay play a protective role to prevent the transistor from being damaged due to the high voltage generated by the self-inductance when the relay is cut off and released.
Miniature toggle switch starts will depend entirely on the primary winding of a rotating magnetic field, there is no so-called phase, because of the capacitor and auxiliary windings in the motor speed after reaching a speed, through the centrifugal switch and separation, they have not working, this kind of motor fatal flaw is that once you take some high loading equipment, such as air compressors, often around will slow down, and then through the auxiliary winding start again, so it is not suitable for many places, usually only have some use in the place such as fan, but has been replaced by the mentioned in the third class of the motor.
This is the micro toggle switch transistor dredge problem, also need to be affirmed in more problems, please pay more attention to us.
