The 12TW1-3 Toggle Switch from Honeywell is a miniature-type toggle switch. The TW series toggle switches are designed to meet military specifications and are well-suited for military, aerospace and other demanding applications where space behind the panel is limited. These applications include environments where the panels are subjected to vibration, dust, splashing water and temperature extremes. Toggle Switches are manually actuated by means of a projecting lever, such as mechanical lever, handle or a rocking mechanism. These electrical switches are available in many different styles and sizes. They are generally used in industrial machinery and construction equipment, military and commercial aviation, test instruments, agricultural machinery, process control, and medical instrumentation, among others.

Compact and lightweight, this 12TW1-3 Honeywell Toggle Switch features pull-to-unlock lever to prevent accidental operation. The molded-in terminals of this DPDT Toggle Switch are plated for soldering. This toggle switch is also available in special on-on-on circuitry.
