Reference table for customizable rated voltage and rated current:

Rated voltage	Rated current (A)
	Non-inductive load				Inductive load
	Resistive load		Lamp load		Inductive load		Motor load
	NC	NO	NC	NO	NC	NO	NC	NO
125VAC	10		3	1.5	10		5	2
250VAC	5		2	1	5		3	1.0
480VAC	3		1.5	0.8	3		1.5	0.8
600VAC	1		1	0.5	1.5		1	0.5
8VDC	10		6	3	10		6

125VDC	0.8		0.2	0.2	0.8		0.2
250VDC	0.4		0.1	0.1	0.4		0.1

Note:

Power factor of inductive load is above 0.4 (AC). The time constant is below 7ms (DC).
The inrush current of lamp load is 10 times that of steady state current, and the inrush current of motor load is 6 times that of steady state current.

Tips: Electrical considerations for limit switches
In the case of AC and DC, the capacity of limit switch is very different, so please use the limit switch within the rated range.
In the case of DC, the control capacity of the limit switch is extremely low. This is mainly due to the fact that direct current does not have a zero point (current zero intersection) like alternating current, and once an arc is generated, it is difficult to disappear. The arc time is long and the current direction is fixed, so there will be a migration of the contacts. Contacts cannot be disconnected due to unevenness.
In the case of including induction, a reverse induced voltage is generated. The higher the voltage, the greater the energy, and the greater the loss and migration of the contact. Therefore, use the limit switch within the rated conditions. Use a limit switch for micro-loads in the case of small voltages and currents. Using general silver contacts may reduce contact reliability.
