Abstract
A protection switch device has power poles whose mobile contacts are carried by a contact-holder, a magnetically and/or thermally tripped protection system to detect overloads or overcurrents on each pole current path and an actuator mechanism operated manually by an actuator button. This mechanism includes a permanent magnet lever cooperating with a magnetizable contact operating arm and a magnetizable tripping arm, movement of which is controlled by the protection system. The mechanism also includes a manual actuator for directly opening the power contacts of a overload relay or like device or, after turning the manual actuator button, opening an auxiliary contact to interrupt the current in a coil of a solenoid actuating a contactor/overload relay or like device.
