SPDT PCB Terminal Micro Hloov

Ib qho SPDT (Ib Tug Ncej Ob Qhov Ncauj) PCB davhlau ya nyob twg micro hloov nrog TSIS MUAJ (Nquag Qhib) thiab NC (ib txwm Kaw) cov neeg sib cuag thiab 3 tus pins yog hom tshwj xeeb ntawm snap-action hloov tsim los txuas ncaj qha mus rau cov ntawv luam tawm Circuit Board (PCBs). Qhov kev teeb tsa no suav nrog peb lub davhlau ya nyob twg pins rau soldering mus rau PCB, muab kev sib txuas hluav taws xob rau qhov hloov. Nov yog cov ncauj lus kom ntxaws txog nws cov yam ntxwv thiab kev siv:

Ntsiab nta thiab tsim:

SPDT Configuration:

SPDT qhia tau hais tias qhov hloov pauv muaj ib qho chaw nkag (Common) thiab tuaj yeem txuas mus rau ob qhov sib txawv ntawm cov khoom siv hluav taws xob (Nquag Qhib thiab Nquag kaw). Qhov no tso cai rau qhov hloov mus tswj ob lub voj voog sib cais lossis cov teeb liab txoj hauv kev.

PCB Terminal Mounting:

Tsim los rau kev sib koom ua ke ncaj qha mus rau PCBs, qhov hloov pauv lub davhlau ya nyob twg tus pins yooj yim rau soldering mus rau lub rooj tsav xwm Circuit Court. Txoj kev sib koom ua ke no ua kom yooj yim cov txheej txheem sib dhos thiab txhim kho qhov chaw ua haujlwm hauv cov khoom siv hluav taws xob thiab khoom siv.

TSIS MUAJ thiab NC Contacts:

Qhov hloov pauv muab ob qho tib si Qhib (NO) thiab Nquag Kaw (NC) hu. Thaum qhov hloov pauv nyob rau hauv nws lub xeev tsis ua haujlwm (tsis ua haujlwm), NC kev sib cuag raug kaw, tso cai rau tam sim no ntws los ntawm txoj kev ntawd. Thaum lub tshuab hluav taws xob ua haujlwm, NC kev sib cuag qhib, thiab tsis muaj kev sib cuag kaw, hloov lub xeev hluav taws xob.

Snap-Action Mechanism:

Siv lub snap-action mechanism rau kev hloov ceev thiab txhim khu kev qha. Cov txheej txheem no ua kom ntseeg tau tias qhov hloov pauv hloov pauv sai sai nrog lub zog ua kom tsawg, muab cov lus qhia tactile thiab hnov ​​​​clicks kom paub meej tias kev ua haujlwm.

SPDT PCB davhlau ya nyob twg micro hloov nrog NO thiab NC kev sib cuag thiab 3 tus pins yog cov khoom siv ntau yam siv nyob rau hauv ntau hom kev siv hluav taws xob uas muaj peev xwm hloov tau thiab txhim khu kev qha yog qhov tseem ceeb. Nws kev koom ua ke rau PCBs yooj yim sib dhos, txhim kho qhov chaw ua haujlwm, thiab ua kom muaj kev ua tau zoo hauv kev lag luam automation, cov neeg siv khoom siv hluav taws xob, tshuab tsheb, thiab cov khoom siv hauv tsev. Los ntawm muab kev txhim khu kev qha hloov ntawm ntau lub voj voog hluav taws xob, cov keyboards no pab txhawb kev ua haujlwm thiab kev nyab xeeb ntawm cov khoom siv hluav taws xob thoob plaws ntau yam kev lag luam.
