Note 1. Unless otherwise specified, a tolerance of ±0.4mm applies to all dimensions.

Note 2. The operating characteristics are for operation in the A direction (

).

Precautions

★Please refer to "Basic Switches Common Precautions" for correct use.

●Handling

Do not apply excessive shock. Doing so may cause damage to

the Switch's internal components because they designed for a

small load.

●Soldering

• Terminal connections

Complete the soldering at the iron tip temperature between

250 to 350°C (60W) within 5 seconds, and do not apply any

external force for 1 minute after soldering.

Apply minimum amount of flux required. It may result in

contact failure once the flux penetrates into the internal part of

the Switch.

●Mounting

Use M3 mounting screw with plane washers or spring washers to

securely mount the Switch. Tighten the screws to a torque of

●Mounting Direction

For a Switch with an actuator, mount the Switch in a direction

where the actuator weight will not be applied to the Switch. Since

the Switch is designed for a low operating force, its release force

is low. Therefore, release failure may occur if unnecessary force

is applied to the Switch.

●Using Micro Loads

Using a model for ordinary loads to open or close the contact of

a micro load circuit may result in faulty contact. Use models that

operate in the following range. However, even when using micro

load models within the following operating range, if inrush current

occurs when the contact is opened or closed, it may increase the

contact wear and so decrease durability. Therefore, insert a

contact protection circuit where necessary. The minimum

applicable load is the N-level reference value. This value

indicates the malfunction reference level for the reliability level of

60% (

(JIS C5003)

The equation,

estimated malfunction rate is less than

with a reliability level of 60%.
