Description

Technical Field

[0001] The utility model relates to the technical field of circuit signal detection, in particular to a circuit signal detection device for a seat control mechanism. Background Art

[0002] The control mechanism is the core control component of the seat, which is used to start the seat workflow when the aircraft encounters an emergency. By pulling the handle, the mechanism generates electrical and mechanical signal inputs, which act on other corresponding mechanisms to start the seat function. During the repair process, the control mechanism needs to be disassembled and inspected, and then reassembled. After assembly, the reliability of the signal output of the nine micro switches installed inside the product needs to be tested. The specific operation process is to pull the handle and restore the mechanism to the initial position, switch the switch back and forth between the "on" and "off" positions, and check whether the output signal of the switch is reliable.

[0003] Usually, the on-off state of the circuit is directly measured by a multimeter. However, since the control mechanism needs to monitor the on-off switching of nine circuits in real time throughout the entire process during the test, the measurement with a multimeter is single-purpose and lacks timeliness.
