How do Trapped Key Interlocks Work?

Trapped Key Interlocks get their name from a series of keys that are released in a pre-designated sequence to protect both people and equipment from hazardous output or situations. You’ll find a trapped key interlock system in most industries where critical but sensitive energy sources need to be isolated before a technician can use or maintain certain pieces of machinery. Trapped key interlock switches and supporting components resolve a number of safety issues presented by electrical interlocking products in highly dusty, wet or corrosive environments.

  • Trapped key interlocks operate where electrical components cannot, eliminating the risk of explosive hazards, electrical incidents and dust build-up.
  • Each device is supplied with a unique code, guarding your business, your people and your assets against tampering.
