Note: The above values are initial values.
*1. The withstand voltage is the value when a separator (see "Common Accessories for Microswitches") is used.
*2. The value is for the free position and full travel position for Micro Switches type, and for the full travel position for lever type.
The contacts make or break within 1 ms.
