Precautions

Be sure to read the precautions and information common to all Snap Action and Detection Switches, contained in the Technical User’s Guide,

“Snap Action Switches, Technical Information” for correct use.

■ Correct Use

Terminal Connection

To solder the lead to the solder terminal, apply a soldering iron rated

at 60 W max. quickly (within 5 seconds) with the actuator at the free

position.

Note that applying a soldering iron for too long a time or using one

that is rated at more than 60 W may degrade the switch characteris-

tics.

Use an appropriate mating connector for #187 or #250 quick connect

terminals.

Specifications Approved by TÜV Rheinland

According to EN61058-1

Operation

Make sure that the operating body pushes the switch actuator with

an adequate force when the switch is to be operated, and that it does

not touch the actuator when the switch is released.

Do not change the operating position by modifying the actuator.

Do not use the switch in a application where the operating speed is

extremely slow or the actuator is set in the midpoint between the free

position and operating position.

Install the pin plunger switch so that the operating force is applied in

alignment with the stroke of the actuator. The switch should be set so

that its stroke is in the range of 60 to 90% of the rated OT (minimum

value) when the switch has been operated.

■ Cautions

Insulation Distance

According to EN61058-1, the minimum insulation thickness for this

switch should be 1.1 mm and minimum clearance distance between

the terminal and mounting plate should be 1.0 mm. If the insulation

distance cannot be provided in the product incorporating the switch,

either use a switch with insulation barrier or use a separator to

ensure sufficient insulation distance.
