Here are some more information for Microswitch Switches Gear:
During inspection and before removing any accumulated dirt, aircraft mechanics must closely observe the area being inspected while the wingtips are gently rocked up and down. Excessive motion between normally close-fitting landing gear components may indicate wear, cracks, or improper adjustment. If a crack exists, it will generally be indicated by dirt or metallic particles which tend to outline the fault. Seepage of rust inhibiting oils, used to coat internal surfaces of steel tubes, also assists in the early detection of cracks. In addition, a sooty, oily residue around bolts, rivets, and pins is a good indication of looseness or wear.
a. Thoroughly clean and re-inspect the landing gear to determine the extent of any damage or wear. MRO teams may discover that some components require removal and complete disassembly for detailed inspection. Other components may require the assistance of stress engineers to do a specific check using an ndt inspection process such as dye penetrant inspection, magnetic particle inspection, radiographic, ultrasonic, or eddy current inspection. The frequency, degree of thoroughness, and selection of inspection methods are dependent upon the age, use, and general condition of the landing gear.
b. Qualified technical staff must inspect the aircraft or landing gear structure surrounding any visible damage, to ensure that no secondary damage remains undetected. Forces can be transmitted along the affected member to remote areas where subsequent normal loads can cause failure at a later date.
c. Prime locations for cracks on any landing gear are bolts, bolt holes, pins, rivets and welds. The following are typical locations where cracks may develop.
d. Most susceptible areas for bolts are at the radius between the head and the shank, and in the location where the threads join the shank.
e. Cracks primarily occur at the edge of bolt holes on the surface and down inside the bore.
f. The usual types of failure in riveted joints or seams are deformation of the rivet heads and skin cracks originating at the rivets' holes.
g. Cracks and subsequent failures of rod ends usually begin at the thread end near the bearing and adjacent to or under the jam nut.
h. Cracks develop primarily along the edge of the weld adjacent to the base metal and along the centerline of the bead.
i. Elongated holes are especially prevalent in taper-pin holes and bolt holes or at the riveted joints of torque tubes and push-pull rods.
j. Deformation is common in rods and tubes and usually is noticeable as stretched, bulged, or bent sections. Because deformations of this type are difficult to see, feel along the tube for evidence of this discrepancy. Deformation of sheet-metal web sections, at landing-gear component attachment points, usually can be seen when the area is highlighted with oblique lighting.
When an aircraft experiences a hard or overweight landing, the aircraft mechanics should perform a special structural inspection of the aircraft, including the landing gear. Landing gear support trusses should be inspected for cracked welds, sheared bolts and rivets, and buckled structures. Wheels and tires should be inspected for cracks and cuts, and upper and lower wing surfaces should be inspected for wrinkles, deformation, and loose or sheared rivets. If any damage is found, a detailed inspection is recommended.
Landing gear retraction tests
Periodically perform a complete operational check of the landing gear retraction system. Inspect the normal extension and retraction system, the emergency extension system, and the indicating and emergency warning system. Aerosopace systems engineers must determine that the actuating cylinders, linkage, slide tubes, sprockets, chain or drive gears, gear doors, and the up-and-down locks are in good condition and properly adjusted and lubricated, and the wheels have adequate clearance in the wheel wells. In addition, an electrical continuity check of micro-switches and associated wiring is recommended. Only qualified technical personnel should attempt adjustments to the gear position and warning system micro-switches. Follow the manufacturer's recommendations.

Repairing and Maintaining Your Treadmill
Most operating problems are usually easily seen, detected and repaired. If the cause of a problem is not obvious, follow a logical process of checking each component in the system.
Repair of Your Treadmill
I t would be impossible for me to list every problem for every manufacturers treadmill in this report, but here are some common problems:
Walking belt is not centered. See preventive maintenance procedure for centering belt.
No power, check that the unit is plugged in to a live outlet, ALWAYS USE CAUTION when dealing with electricity. Try another outlet if you need to.
If you know the outlet is live, unplug the unit and check the fuses, you may need to lift the cover for this.
IF you have power but the motor does not turn you either have a bad power supply or the motor brushes are worn. Contact the manufacturer for information.
If the motor is turning make sure the drive belt is not loose or broken. Tighten or replace as needed.
Walking belt moves, but there is a loud grinding noise.
Loosen the belt and see if the noise goes away, if it does you may have a bad front roller. Sometimes you can spray the bearing in the roller with a lubricant like WD40 and this will solve the problem, but you may need to replace the roller.
If the noise does not go away then the motor bearings are probably bad and you will have to replace the motor.
Elevation does not work, unit will not go up or down or is stuck in the elevated mode.
Unplug the unit and check the elevation motor fuse, replace if necessary. Check the elevation system for broken chains or cables, make sure something hasn't gotten caught in the gears.
If your unit is equipped with limit switches for the up and down limits check them to be sure they are not engaged. These are usually little microswitches located around the elevation gears.
ALWAYS LOOK FOR LOOSE OR BROKEN WIRES FOR ANY PROBLEM YOU ARE HAVING.
You have power to the treadmill but the control panel does not work.
If your unit requires a key or a magnet make sure it is inserted correctly.
You may have a bad control panel, and you will need to replace it.
Check, for broken or loose drive belts underneath the cover.
The treadmill will run for a short time then either pops a fuse, or breaker or just stops.
Probably the belt or deck, or both are worn and need to be replaced. Try lubricating the deck first. If this doesn't help then you will need to replace the worn parts.
Maybe the belt is too tight and is causing the motor to draw too much current. Try the belt tightening procedure under preventive maintenance.
