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
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
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-
Use an appropriate mating connector for #187 or #250 quick connect
Specifications Approved by TÜV Rheinland
According to EN61058-1
Appropriate Cable Size (mm2)
0.75, 1.25, 2.0
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.
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.
