Machine Safety Switches – SI-LS31H Series Overview Actuator head may be rotated in 90° increments. Series SI-LS31H safety interlock switches have a built-in hinged lever actuator that mounts to a hinged door or flap to detect its being opened. The actuator head may be rotated on the interlock body in any of four positions (see Figure 1). Mechanical Installation 1.

Machine Safety Switches – SI-LS31H Series CAUTION . . . Electrical Installation Two safety switches must be used for each interlock guard to achieve control reliability or Safety Category 4 (per ISO 13849-1, EN 954-1) of a machine stop circuit. Use of only one safety switch per interlock guard is not recommended.
