Embodiment Construction

[0022] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.

[0023] Such as figure 1 As shown, it is a structural schematic diagram of an embodiment of the key switch on-off counting circuit of the present invention. A key switch on-off counting circuit is used for testing the effective on-off times of a key switch 200 , including a key switch life testing device 100 , a delay switch module 300 and a counting module 400 . The key head 140 of key switch life testing device 100 (such as figure 2 shown) is aligned with the key switch 200, the key switch 200 is connected to the delay switch module 300, the delay switch module 300 is connected to the counting module 400, and the key switch life testing device 100, the delay switch module 300 and the counting module 400 are respectively connected to the power supply.

[0024] Such as figure 2 As shown, the key switch life testing device 100 uses a finger...

Abstract

The invention discloses a key switch on-off counting circuit. The key switch on-off counting circuit comprises a key switch service life testing device, a counting module and a delay switch module. During testing, when a key switch is continuously turned on and off once, tuning-on time of the key switch turned on under the action of the key switch service life testing device reaches first delay time set by the delay switch module, and second staying time of the key switch which is turned on and then turned off under the action of the key switch service life testing device reaches second delay time set by the delay switch module, the state of the delay switch module is turned over twice, and the counting module carries out counting once. The testing hidden hazard that the key switch is not locked when turned on or cannot be turned off is avoided, effectiveness of testing of the on-off frequency is guaranteed, testing accuracy is high, and labor intensity is lowered.

Description

technical field [0001] The invention relates to the field of switch detection, in particular to a key switch on-off counting circuit. Background technique [0002] Lamp lighting can be seen everywhere in modern society. When the lamp is in use, it will operate the button switch of the lamp, so the reliability of the button switch is very important, and the life of the switch must be considered in the design of the lamp. [0003] At present, when testing the life of the number of switches, a button head like a finger is generally used, and the circuit control is used to make the button head move up and down. At this time, the button to be tested is placed under the button head of the button tester, and the button and The distance between the button heads of the instrument. When the button head of the key test instrument tooling runs down to the end, press the button switch once, and then stay for a while. When the button head moves up to the top, stay for a while, and then mo...
