Electromagnetic device for cameras

An electromagnetic device for cameras, comprising:

• a baseplate;
• a yoke mounted on said baseplate and having a contact surface;
• an armature having a contact surface that opposes said yoke contact surface;
• an armature shaft having a first end attached to said armature so as to extend perpendicularly to said armature contact surface, said armature shaft having a catch spaced from said first end;
• an armature lever slidably mounted on said armature shaft so as to be movable between said armature and said catch;
• a biasing member that applies a force to said armature lever to bias said armature lever away from said yoke and toward said catch;
• a coil provided on said yoke to selectively excite said yoke, when in an excited state, said armature lever being attracted toward said yoke causing said armature contact surface to come into contact with said yoke contact surface, and when in an unexcited state, said armature becoming disengaged from said yoke;
• said armature lever including at least one opening for use in applying an elastic adhesive between said armature lever and said armature.
