Honeywell PTKBC2221B Microswitch Selector Switch

The Honeywell PTKBC2221B Microswitch Selector Switch with Keys is a keyed selector switch that integrates a Honeywell Micro Switch mechanism for position sensing in control panels. The unit ships with keys, enabling secure operation and preventing unauthorized changes to the selected position. Identified by the PTKBC2221B model number within the PTKBC2221 family, this device combines a mechanical selector with a microswitch output to provide a defined electrical signal for downstream control circuits. Designed for use in industrial and commercial control panels, the PTKBC2221B offers a compact form factor and the reliability associated with Honeywell’s Micro Switch line. When installed as part of a panel, it can serve as a manual selector input that yields a corresponding switch state to the control logic, facilitating straightforward on/off or mode-selection schemes depending on the surrounding circuitry.
