ABSTRACT:
In a reed switch comprising an envelope, first and second stationary terminals, and an armature supported elastically on the second stationary terminals in such a manner that the innermost end portion of the second stationary terminal and one end portion of the armature are opposite to each other with a magnetic gap, each of the one end portion of the armature and the innermost end portion of the second stationary terminal is larger in sectional area than the other portion thereof, thereby to decrease the magnetic resistance of the magnetic gap and to increase the closing power of the switch. According to another aspect of the invention, the reed switch has a back stop for detaining the armature when the switch is opened.
