[*1] Weight represents thst of Double throw (D), Front (F) and Back (B) type.
[*2] Even with the back (B) connection type, front wiring is to be performed for the control circuit and auxilliary circuit.
[*3] Opening time is the time when the contact is not in the either make or break position.
Switching time is the time from control signal ON to contact making
