However, to warrant a long and trouble-free service period, we advise that a visual inspection of the contacts and bearing points be carried out at regular intervals.With Celeste being a breakout hit of the 2018 release window, there’s been a good deal of anticipation surrounding Earthblade, the next video game from developer Extremely OK Games. The earthing switches supplied by Hapam are designed so as to ensure that they are virtually maintenance free. Hapam provides clear installation instructions and assembly drawings.

The construction is designed so that all earthing switches can be installed and adjusted at site very easily, without the need of any special tools. The earthing switches are pre-assembled and adjusted in our works as complete as possible. Hapam maintains a quality assurance system according to ISO 9001, certified by DEKRA (previously known as KEMA). The earthing switches are designed and tested in accordance with latest IEC specifications. The drive mechanism also houses the auxiliary contacts for position indication. In case only one drive mechanism is used for three-pole operation, the poles are interconnected by means of adjustable coupling rods. The earthing switch can be single-pole or three-pole operated by means of a motor-operated drive mechanism or a manual-operated drive mechanism. The earth blade consists of an Aluminum tube, provided with silver-plated copper contacts at both ends. The earthing switches can be equipped with insulators in accordance with IEC, ANSI or DIN specifications. All steel parts of the earthing switch are hot-dip galvanized.

The base plate is made of steel plate on which the support insulator, earth blade and bearing plate are installed. Each pole consists of a base plate, one support insulator and an earth blade that moves in a vertical plane. The free-standing earthing switch consists of three poles.
