1. Avoid pressing the rod followed by sudden release of the rod.
2. The contact performance specifications refer to the built-in contacts.
3. The rated operational current indicates the current value to be used under the rated operational voltage and specified conditions (make and break current, switching frequency, and electrical endurance).
For 240VAC: The setting is based on 10× make (cosφ = 0.6–0.7) and 1× break (cosφ = 0.3–0.4). A rated operational current of 1A means 10A for making and 1A for breaking. For 115VDC: The setting is based on 1× make and 1× break, specified for inductive loads (L/R = 40ms).
4. Temperature characteristics are values under conditions without freezing or condensation.
