The housing of the PTT button is made of impact-resistant, fibreglass-reinforced plastic and is ideally suited for robust use. Thanks to the splash water protection, it can also be used in a damp environment or in daily use in outdoor areas without any worries. There is a fastening clip on the back for attachment. The large, fluorescent transmit button allows safe operation even in hectic situations and the additional mountable protective ring prevents the button from being pressed accidentally.
