ABSTRACT:
An electromagnetic brake includes a housing, a pin, brake springs urged against the pin, a handle pivotably secured to the pin, a coil, a moveable armature plate, a moveable friction disc, a trigger switch on the housing and including a projecting contact and a pivotal trigger, steel balls in the half holes of the housing and the handle, and a rod fixedly projecting out of a slot of the handle. In a brake released position, the rod is at one end of the slot with the coil being energized. The handle is adapted to pivot to move the other end of the slot to engage with the rod, the handle contacts and pivots the trigger to enable the trigger switch so as to de-energize the coil, and the springs apply an expansion force to urge against the pin for causing the friction disc to apply brake to a shaft.
