How to Use of OMRON Micro Switches

OMRON Micro Switches Regarding Installation

Use M3 screws for mounting and securely attach using flat washers, spring washers, etc. The tightening torque should be 0.39 to 0.59 N m.

Cautions and Prohibitions of OMRON Micro Switches

Safety Precautions of OMRON Micro Switches

Micro Switches Regarding soldering

As a guideline, the soldering time for connecting to the soldering terminals should be less than 5 seconds with a soldering iron of 60W (tip temperature +250 to +350°C), and no external force should be applied for 1 minute aftersoldering
. Use the minimum amount of flux possible. If flux gets inside the switch, it may cause contact failure.
Micro Switches Connection to #187 tab terminals
: Use a #187 tab receptacle and insert it straight into the terminal.
Applying excessive external force to the side or top/bottom of the terminal may cause deformation of the terminal and damage to the housing.
Micro Switches Connection to #250 tab terminals
: Use a receptacle for #250 tabs and insert
it straight into the terminal. Applying excessive external force to the side or top/bottom of the terminal may cause deformation of the terminal and damage to the housing.
