Honeywell 104TL2887-3 Operator Controls
The Honeywell 104TL2887-3 operator controls switch is a distinctive TL Series variant intended for applications that need a rugged mechanical interface with relatively low electrical load. Public technical data identifies this model as a 4PDT panel-mount toggle with an On-On function, 100 mA current rating, 115 V AC, and 28 V DC capability. That makes it especially relevant for signal-level or low-current switching duties rather than heavy power control.
Why the 104TL2887-3 Is Different
Many TL Series switches are associated with higher current capabilities, but the Honeywell 104TL2887-3 operator controls switch stands out because distributor data places it in a low-current switching category. This matters in control logic, instrumentation, avionics-adjacent interfaces, or specialized industrial control systems where signal integrity and dependable mechanical action are more important than large load handling.
Technical Characteristics
DigiKey lists the exact part as a 4PDT On-On switch with IWTS termination, environment sealing, 17.27 mm standard round actuator, 15/32-32 bushing thread, and an operating range of -65°C to 71°C. Honeywell’s TL Series documentation supports the family-level context: MIL-DTL-3950 qualification, bonded seals, multiple pole options, and design suitability for shock, vibration, and harsh environmental exposure.
Application Fit
The Honeywell 104TL2887-3 operator controls model is best understood as a rugged, low-current control switch for environments where mechanical reliability cannot be compromised. It may be relevant in control cabinets, specialized transport equipment, aerospace-support systems, and equipment interfaces where multiple low-level circuits must transfer together between two states.
Because it combines sealed construction with a low-current specification, it occupies an interesting space in the TL lineup. It is not just durable; it is also appropriate for more delicate electrical control roles.

FAQ
What electrical role is the Honeywell 104TL2887-3 best suited for?
It is especially suitable for lower-current control or signal switching where rugged mechanical reliability is still essential.
What switch function does it use?
DigiKey lists the part as a 4PDT On-On switch.
Is it sealed like other TL Series parts?
Yes. It is identified as environment sealed and belongs to Honeywell’s sealed TL Series family.
Does it use IWTS termination?
Yes. Public distributor data lists IWTS as the termination style for this model.
Why would someone choose this part instead of a higher-current TL switch?
Because some systems need the ruggedness of the TL platform but operate at lower current levels and more control-oriented electrical loads.
