Issue:
Understand the function of an electrical interlock

Product Line:
Safety Switch Accessories

Environment:
Electrical Interlocks

Cause:
Understand the funcion of an electrical interlock

Resolution:
An electrical interlock kit consists of an industrial snap switch mounted on an operating mechanism. The snap switch will contain either 1NO/1NC or 2NO/2NC sets of contacts, based on the catalog number of the electrical interlock kit. Kits ending in the numeral "1" will contain 1NO/1NC contacts and kits ending in the numeral "2" will contain 2NO/2NC sets of contacts. The kit is mounted to the internal operating mechanism of a safety switch. When the safety switch handled is operated from the OFF position to the ON position, the contacts change status: The NO contacts close and the NC contacts open. The kits can be used to be able to monitor the operating status (ON or OFF) from a remote location via control wiring, or be used to drop out a coil in a motor starter.
