Instructions
Contact Bounce
When the button is reset by pulling or turning, the NC main contacts 
will bounce. When pressing the button, the NO monitor contacts will

When designing a control circuit, take the contact bounce time into 
consideration (reference value: 20 ms).
LED Illuminated Switches
An LED lamp is built into the contact block and cannot be replaced.
