4. Limit switch (switch) : limit switch is 3 phase induction motor in accordance with the production of mechanical motion stroke position and action of small current switch. Its choice is mainly according to the requirement of the mechanical position of switch type, the contact number, voltage type, the model is determined by the voltage electric current rating requirements. Machine tool commonly used have LX2, LX19, JLXK1 and LXW11, JLXK - 11 l micro switch, etc. For fast, high sensitivity, schedule control, the rotor proximity switch can be used. Proximity switch is also known as non-contact limit switch. It is caused by the moving parts of electromagnetic field change and action. Proximity switch long life and good reliability, generator accuracy and price limit switch. 5, automatic air switch, automatic switch is spare parts also called the automatic air circuit breaker. Automatic switch on the machine is widely applied. This is because the automatic switch can connect or breaking normal working current, can automatically breaking through cutting or short-circuit current, breaking capacity is big, has under voltage diesel generator set and overload short circuit protection. 

Select wholesalemotor.blogspot.com automatic switch should be considered the main parameters: rated voltage, rated current and the limit of the allowed to cut off the current, rotor etc. Automatic switch trip rated current should be equal to or greater than the load allows the long-term average of current; The limits of automatic switch breaking ability than, at least equal to the maximum short-circuit current circuit; Automatic switch trip current setting should be according to the following principles: under voltage trip rated voltage should be equal to the rated voltage of main circuit; Thermal trip setting current and load) is equal to the rated current alternator generator of the object; Electromagnetic trip of the instantaneous electric generator tripping current setting should be greater than the load peak current in normal working conditions; generator Protect motor, electromagnetic trip decide the instantaneous tripping current of motor starting current of 1.7 times. Machine tool commonly used automatic air switch such as DZ series, the series of DW.
