Mechanically coded actuators use two independent operating elements to minimize intentional tampering or defeat.

• Compact metal style switches are designed for limited space requirements in rugged environments
• SI-LM40MKH models are available with rigid and flexible in-line actuators.
• SI-LM40MKV models have a trumpet-style actuator.
• Rotating head requires little or no tools to adjust to four positions.
• Design meets positive opening requirements for safety interlocks.
