Chitetezo cha kukweza kosinthira pazitsulo ndizitsulo zotetezera zomwe zimaphimba zomangira zoyikapo kuti ziziteteze kuzingwe zilizonse zamoyo.

Gawo lirilonse limakhala ndi mapulagi amiyendo yolumikizidwa ndi zotsekemera zotsekemera kuti zigwirizane mosavuta ndi ma 25mm kapena 20mm ma kondomu ndi zisoti zomangira. Zisoti zomangira ziyenera kukhazikitsidwa kuti zitsimikizire IP Rating.

Mphamvu ndi chivundikiro cha Resistant Resist chimapulumuka kugogoda kovuta kwambiri munjira iliyonse. Magawo awiriwa adasindikizidwa ndi chidutswa chimodzi cha nyengo.

Chitetezo, bowo la 7mm m'mimba mwake limaperekedwa kuti mutsekeze lever pamalo ake.

Ma bariers akuya kwambiri amateteza lever wogwirira ntchito ku nkhanza kapena kusintha mwangozi.

Ma Allunits amatsatira IEC60947-3.

Migodi ndi Mphamvu, kumwera, Australia, Kuvomerezeka.

Mitundu yoyera ndi Gray & White.
