Uphawu lokhuseleko lokufakela iiswitshi kwizakhiwo zesinyithi zizigqubuthelo zokukhusela ezigubungela izikrufu zokufakela ezisisiseko ukuze zikhuseleke ngokupheleleyo kuzo naziphi na iintambo eziphilayo.

Iyunithi nganye inikwe iiplagi zemibhobho eneeskrufu kunye nezinciphisi ezineeskrufu ukuze kube lula ukuqhagamshela kwiikhombi ezingama-25mm okanye ezingama-20mm kunye nezikrufu. Izikrufu kufuneka zifakelwe ukuqinisekisa i-IP Rating.

Isiseko kunye nesigqubuthelo esimelana nempembelelo siya kusinda kwiingxaki ezinzima phantse kuyo nayiphi na into efakelweyo. La macandelo mabini atywinwe nge-gasket yesitywini semozulu yeqhekeza elinye.

Ngenxa yokhuseleko, kukho umngxuma onobubanzi obuyi-7mm oza kutshixa i-lever kwindawo ethi OFF.

Iibhari ezibunjiweyo ezinzulu zikhusela i-lever yokusebenza ekuxhatshazweni ngokomzimba okanye ekutshintsheni ngengozi.

Zonke iiyunithi ziyahambelana ne-IEC60947-3.

Imigodi kunye neMandla, emazantsi, eOstreliya, ukuVunywa.

Imibala eqhelekileyo yiGrey & White.
