Specifications
■ Characteristics
Note: 1. Data shown are of initial value.
2. The dielectric strength shown is measured using a separator between the switch and metal mounting plate
3. For pin plunger models, the above values apply for use at the free position, operating position, and total travel position. For models with
levers, the values apply at the total travel position.
■ Ratings (reference values)
D2SW-3
D2SW-01
Note: 1. The resistive load ratings apply under the following test conditions:
Ambient Temperature = 20
±2°C, Ambient Humidity = 65±5%, Operating frequency = 30 operations/min.
2. The above current ratings are the values of the steady-state current.
3. Inductive load has a power factor of 0.7 min. (AC) and a time constant of 7 ms max. (DC).
4. Lamp load has an inrush current of 10 times the steady-state current.
5. Motor load has an inrush current of 6 times the steady-state current.
