This Flush Mount Keyswitch without stop provides keyed control for commercial and industrial door operator systems. The flush mount design allows the keyswitch to sit close to the mounting surface for a clean control setup. This version does not include a stop function. This keyswitch is used with compatible rolling doors, overhead doors, garage doors, service doors, and motorized commercial door systems that require keyed access control without a stop button. * Keyed-alike option: Available at an additional cost for projects that need multiple keyswitches to work with the same key.
