Magnetic Lead Switch Type
Proximity Switch

This is a proximity switch that operates by magnetic force without a drive power supply. Custom-made products are available at low cost.

Lead switch -adjacent switch


This is a proximity switch that operates by magnetic force. The operating distance can be set by magnetic force with this proximity switch, and custom-made products are also available, such as changing the length of the wires, or the terminal processing, etc.


  • - Magnet operating type that operates by magnetic force
  • - Adoption of a reed switch realizes low cost
  • - Drive power supply is not required

Operation method

NO type = Contacts close (ON) only when detection object (magnet) approaches
NC type = Contacts open (OFF) only when detection object (magnet) approaches
SH type = This type uses a method to memorize the operating state (ON or OFF) by approaching the detection object (magnet) even after the detection object passes by.
