Abstract

The pull-down actuator for an electrical safety switch has a pivot mounted lever Ä3Ü that can be moved through an arc. The base of the lever has a ball Ä6Ü and this is sandwiched between two half housing elements Ä4Ü. Inserted into the housing is a hemi-spherical bearing shell Ä8Ü that is designed to fit around the ball. A locking screw Ä9Ü sets the contact pressure relative to a coil spring Ä13Ü in the base.
