1 2 R Operation Actuator Alignment Guide Actuator alignment guide, easily replaced if damaged, provides an ideal letter box feature for mounting the switch behind a fixed panel. A B C D Blanking plug for unused entry. 2 1 The head rotates 180 to give 4 possible actuator entry points. A distance of 3.0mm or less is required between face of switch and face of actuator for switch to lock. Locking force = 450 lbs (2000 N) maximum Optional Key Release Version The is available with a key to provide emergency override of the switch locking mechanism by a qualified, responsible person. Optional Flat Actuator Allows mounting to flat surfaces. Flexible rubber mounting bushings also allow for some actuator flexibility. Optional Flexible Actuator 1 15 flexibility in any direction. The actuator has 2 set screws for altering and locking adjustable angle. For the Latest Information Try Our Fax Back System at 1/916/431-6544 On the Internet: www.sti.com E-mail: sales@sti.com E113
