Two-way latching device

What it represents

This form identifies the publisher's two-way latching-device arrangement. A two-way latch represents retention associated with more than one movement or position relationship. The electrical contacts operated by that mechanism can still have their own independent state table.

Document the positions that are retained and how the mechanism changes between them. Device tagging connects the latch representation to the operated contacts or actuator.

How to read it

• Document the positions retained by the latch and the changeover action.
• Two-way retention does not imply a two-way electrical contact arrangement.

Information to show or reference

• Identify the associated device, circuit or diagram boundary.
• Document the positions retained by the latch and the changeover action.
• Cross-reference the equipment data, terminal mapping or operating-state legend needed to interpret the form.
