A power dispersion type motor train unit pressure switch feedback detection special tool

Abstract

The utility model discloses a power dispersion type EMU pressure switch feedback detection special frock belongs to pressure switch detection technical field. The wire connection mode of battery compartment and switch plug has ensured the stability of power supply, and the series structure of LED light emitting diode and color ring resistance has formed the clear on-off indication loop, when the pressure switch contact closes, the current forms the complete loop through battery compartment anode, switch plug contact, LED light emitting diode and color ring resistance, and whether the pressure switch function is normal is directly reacted through the bright and dark state of LED, avoids the defect that auditory signal is disturbed by environment, and the standardization butt joint design of special plug assembly and pressure switch pin reduces the operation complexity, improves the environmental adaptability and result consistency of detection process, fundamentally reduces the misjudgment risk caused by human factor, and provides reliable, efficient special solution for EMU brake system pressure switch detection.
