Push-button control desk is intended for commuting electric circuits controlling hoisting mechanisms.
They represent a sealed casing made of thermal-resistant ABS-plastic with buttons.
To ensure sealing of the cable lead-in a protective gland is provided.
There is an O-ring mounted between the casing and the keyboard.
According to its constructive and technical features, PKT series talfer button keyboards meet the requirements of IEC 60947-5-1.
Option of installing 2, 4 or 6 buttons.
PKT casing is made of ABS-plastic being a non-flammable material.
Protective gland at the cable lead-in excludes dust and moisture ingress.
