Abstract
A low profile limit switch utilizes a bowed spring actuator for advancing a bridge contact into and out of contact with a pair of terminal contacts to close and open the switch. The bridge contact is mounted on a glide on an end of the spring and formed from an insulating material. The terminal contacts are spring loaded and maintained in spaced apart and staggered relationship so that only one of the terminal contacts remains in contact with the bridge contact when it is retracted by the bowed spring. A mounting clip including a mounting flange and spaced apart spring loaded arms extending generally perpendicular to the mounting flange is used to mount the switch to a surface proximate an edge without having to obtain any significant amount of vertical clearance above the switch for bolting it to the surface.
