Selection Guide

Choosing a Keylock Switch

Switching Function

Choose a maintained position that stays selected or a momentary position that returns after release. Match the contact arrangement and switching sequence to the control circuit.

Panel Fit

Compare barrel dimensions, panel thickness, body length and terminal clearance. Use the mounting drawing to confirm the panel opening and space behind the panel.

Key Removal

Choose whether the key should be removable in one position or both positions. Include the required removal positions in the ordering specification.

Applications

Equipment Enable Controls

Use a keyed input where the equipment design requires controlled operation or mode selection.

Control Panels

Match maintained and momentary functions to the control circuit and panel layout.

A maintained position stays selected after turning the key. A momentary position returns after release. In the listed functions, parentheses indicate a momentary position, such as OFF-(ON) or ON-(ON).

Check the mounting drawing, panel thickness, barrel dimensions, body length and terminal clearance. A threaded barrel diameter alone does not define the complete panel opening.

The product tables list removal at one position or both positions. Specify the required removal positions with the full model code so the version can be confirmed.

Compare the switching sequence, contact diagram, terminals and mounting drawing. Similar-looking switches can differ in body length and contact operation.
