Introduction

Statement:

The Magnetic Contact consists of a reed switch and a magnet, the reed switch is actuated by a magnetic field.
The electrical specification of reed switch is based on its pull in AT (Ampere-turns) at 20 by resistance loads. When it used on inductance loads such as Relay, Solenoid valve, DC motor etc. which provides excessive transient voltages when ON/OFF will damage the reed switch. MCS-25 Series is designed a Varistor embedded which protect reed switch from the damage of excessive transient voltages.
