Honeywell 112TW1-7 Toggle Switch Specifications and Use Cases
The Honeywell 112TW1-7 toggle switch is a sealed TW Series operator control component engineered for applications that require a clear three-position momentary switching response. This model uses a DPDT circuit and a Mom-Off-Mom switch function, which means both active end positions are momentary while the center position remains off. That switching logic is especially useful when an operator must send short-duration commands without leaving the system latched in either direction.
Technical Profile of the Honeywell 112TW1-7 Toggle Switch
The Honeywell 112TW1-7 DPDT toggle switch is designed for panel mounting and uses a standard round actuator with an actuator length of approximately 17.27 mm. It is rated at 5 A and supports operating voltages up to 125 V AC and 28 V DC. The mounting format includes a 12.40 mm circular panel cutout and a 15/32-32 bushing thread, which helps maintain dimensional consistency in professional installations.
The switch also features environment sealing, which is one of the reasons TW Series parts remain relevant in applications that involve dust, moisture exposure, splashing, or harsh service conditions. The operating temperature range of -65°C to 71°C supports use in both controlled and more demanding technical environments.
Why the Mom-Off-Mom Function Matters
The defining characteristic of the Honeywell 112TW1-7 toggle switch is its momentary on both sides behavior. In practical system design, this means the switch automatically returns from either active direction after the operator releases the lever. That can be very useful in directional controls, jog functions, temporary command input, reversible motion interfaces, and process tasks where a maintained state could be undesirable.
For engineers, this kind of switch function can reduce the risk of unintended sustained activation. For operators, it adds a more controlled and intuitive feel when a command should only exist while the lever is actively held.
Typical Application Areas
The Honeywell 112TW1-7 operator control toggle switch is often considered for industrial machinery, aerospace-related systems, test instrumentation, agricultural machines, process control equipment, and medical instrumentation where compact sealed manual input is preferred. Search demand is especially strong around terms such as momentary DPDT toggle switch, sealed panel mount toggle switch, and Honeywell 112TW1-7 toggle switch.

FAQ: Honeywell 112TW1-7 Toggle Switch
What does Mom-Off-Mom mean on the Honeywell 112TW1-7?
Mom-Off-Mom means the switch returns from either active position when released, while the center position remains off. This makes it ideal for temporary command functions such as jog, directional control, or short-duration activation.
Is the Honeywell 112TW1-7 a maintained or momentary toggle switch?
It is a momentary toggle switch on both active ends. Unlike a maintained switch, it does not stay engaged in either ON direction after the operator releases the actuator.
Why is a DPDT toggle switch important?
A DPDT design allows the switch to control two separate circuits simultaneously. That can be useful in reversing logic, paired control paths, or applications where two channels need to change state together.
Can the Honeywell 112TW1-7 be used in demanding environments?
Yes. Its sealed construction and wide operating temperature range make it suitable for environments where dust, splashing, vibration, and temperature variation are design considerations.
What should be checked before specifying the Honeywell 112TW1-7?
The main points to verify are the required switch function, actuator style, mounting dimensions, current and voltage ratings, and whether a momentary-both-sides action is appropriate for the application. Those details determine whether the switch fits both the electrical logic and the operator experience of the equipment.
