Makita MAC700 pressure switch won't power on?
Pressure switches do not have reset buttons built in. The reset button is usually attached to the frame or cover and marked with amp rating. The pressure switch only responds to pressure in the tank. There is however a switch incorporated in the cover or on one side of the switch. Usually a red button that you pull, red or black switch/knob/lever to turn on top or side. If on/off switch broke off in the off postion, the compressor will act as yours does. Try to find a picture of your switch on ebay using the brand name or shape /look and determine where the switch should be positioned. If the switch is broken or fallen off /lost, replace the pressure switch with generic. Usually about $18. Pay attention to port size, number of ports and pressure cut-out. Good luck
