Lot of 5 HONEYWELL 101SN11 dual-output optical switch (used/tested). Condition is "Used/Tested". Shipped with USPS First Class.

All switches have been 100% tested. These switches each feature dual outputs and are debounced. Switches are optical I am fairly certain.

Both outputs are open-collector and need an appropriate pull-up resistance. Both outputs trigger at the same time, but only share ground for their emitter connections otherwise. Voltage floats to pull-up voltage then goes to GND when switch is depressed.

Operating voltage is 5v max and what they were tested at. All switches provide clean and reliable outputs. Each has been tested with 10k pull-up resistances on the outputs and an oscilloscope.
