Non-Contact Safety Interlock Switches

What Are Safety Interlock Switches?

Safety interlock switches, also referred to as safety switches or safety interlocks, are pivotal devices in ensuring the safety of machinery and equipment, particularly in scenarios involving machine guarding. These switches are designed to prevent accidents and protect operators and maintenance personnel from potential hazards.

The Role of Safety Interlock Switches

A fundamental purpose of safety interlock switches is to establish a connection between the state of a safety guard, door, or access point and the operational status of a machine. This connection ensures that the machine can only operate when specific safety conditions are met. Typically, these conditions are fulfilled when the guard or access point is securely closed and appropriately aligned.
