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 the pin plunger models, the above values apply for use at the free position and total travel position. For the lever models, they apply

at the total travel position. Contact opening or closing time is within 1 ms.

Engineering Data

■ Mounting Holes

All switches may be panel mounted using M2.3 mounting screws with

plane washers or spring washers to securely mount the switch.

Tighten the screws to a torque of 0.23 to 0.26 N·m.
