Switching Device

US Patent:
5811896, Sep 22, 1998
Filed:
Dec 6, 1996
Appl. No.:
8/759728
Inventors:
Boris Grad - Newton MA
International Classification:
H01H 3600
US Classification:
307125
Abstract:
A switching device (10) for an electrical load, particularly for an electrical toy compraising a normally open reed switch (14) and a fixed biasing magnet (15) located at a distance from the glass tube (17) of the reed switch such that the magnetic strength of the biasing magnet in the area of the reed switch has value less than required for switching on of the reed switch and greater than required for switching off of the same switch. The switch can be actuated--closed by applying to this switch an additional magnetic field the same orientation as the biasing magnetic field; the reed switch is closed and remains closed after removing the magnetic field. This switch can be deactuated--opened by applying to the switch a magnetic field with orientation opposite to the orientation of the biasing magnetic field; the reed switch is opened and remains opened after removing the magnetic field.
