#1 This value can change due to the switching frequency, environmental conditions, 

and desired reliability level, therefore it is recommended to check this with the 
actual load. (SX relays are available for low level load switching [10V DC, 10mA 
max. level])

* Specifications will vary with foreign standards certification ratings.
