Q&A
Please note, Aircraft Spruce Canada's personnel are not certified aircraft mechanics and can only provide general support and ideas, which should not be relied upon or implemented in lieu of consulting an A&P or other qualified technician. Aircraft Spruce Canada assumes no responsibility or liability for any issue or problem which may arise from any repair, modification or other work done from this knowledge base. Any product eligibility information provided here is based on general application guides and we recommend always referring to your specific aircraft parts manual, the parts manufacturer or consulting with a qualified mechanic.
All of these switches can be used in a 24 Volts system. Another key aspect to consider for proper switch selection is the current of the system, if the current is less than 250 mA, then the Gold plate option should be selected, otherwise the Silver/Gold Flash can be used. If the system current is unknown, then the Gold Plate version can be used for both low and high current systems.
This is a momentary switch and does not have a middle position.
No, these are not FAA/PMA approved but instead match a military spec that is used in military and Commercial aircraft. Confirm in your aircraft parts manual or with your authorized A&P mechanic to determine if they can be installed in your aircraft.
