What details should be paid attention to when testing the small toggle switch? The specific situation is as follows.
The advantages of the small toggle switch detection method are more intuitive and convenient. The disadvantage is that the current passing through the switch is very small, which can not destroy the oxide film on the contact surface, resulting in a large identification error (too large), so this method is not recommended in the loop resistance detection of high-voltage switch.
Indirect detection by voltage drop method: the voltage drop method is the DC current of the switch socket, the voltage drop between the incoming and outgoing lines of the small toggle switch socket is detected by millivoltmeter, and then the main circuit resistance of the switch socket is calculated by Ohm's law. Use transformer and silicon rectifier to test the circuit. At the same time, as the current passing through the test object is large enough to destroy the metal oxide film on the contact surface, the detection error is reduced, and the measured value is relatively accurate when using the voltage drop method to detect the main circuit resistance of the small toggle switch socket, the voltage drop method is recommended.
Small toggle switch is a kind of switch with small contact interval and quick action mechanism, contact structure of switch action with specified stroke and specified force, cover with shell and drive rod outside.
Impact resistance: durable impact refers to the impact within the range of action characteristics that microswitch will not be damaged by the mechanical impact during transportation or installation. Misoperation impact refers to the impact range that the contact closed due to impact does not separate within the specified time when the microswitch is used.
