Compact Plastic Style Safety Interlock Switches

Mechanically coded actuators use two independent operating elements to minimize intentional tampering or defeat.
Both housing styles are available in two sizes offering different contact configurations.
Rotating head and top or side engagement allows for eight different actuator positions.
Four standard actuators are available, as well as an optional high-extraction-force actuator.
Design meets positive opening requirements for safety interlocks.
IEC IP65 switch housing rating increases to IEC IP67 with addition of a screw to the wiring chamber door.

Features low-profile design for limited space requirements
Allows actuator engagement from four sides or four top positions with rotating head
Available in models with one of these safety output configurations:

SI-LS100 models have two normally closed (NC) and one normally open (NO) contacts.
SI-LS83 models have either one normally closed (NC) and one normally open (NO), or two normally closed (NC) contacts
