  • Cartridge for magnetically operated contacts
    Patent number: 4015226
    Abstract: A pushbutton switch is described in which a pair of contact cartridges containing magnetically operated sealed switches are mounted to an actuator section. The linear motion of the pushbutton is converted to rotary motion by a cam structure mounted in each cartridge and a magnet mounted therein between two switches is thus rotated about a switch axis. By properly polarizing the magnet and by using a magnetic shield, the switches are made to operate as the magnet is rotated to provide a number of possible modes of operation.
