Abstract
A gravity operated switching circuit, having particular application in end of train equipment, allows the microprocessor circuit board in the equipment to be turned off. The circuit turns the power off when the equipment is laid on its side after a predetermined time constant, and when the equipment is again mounted in an upright position, the power is turned on after a different predetermined time constant. A modification of the basic circuit requires a reset button to be manually pressed to restore power after the equipment is again mounted in an upright position.
