The invention relates to a shaft contact device 1 to make an electrical connection between a shaft and an earth point. Device 1 has a bracket 10 for connection to a point spaced from the rotating shaft, base member 20 mounted on the bracket 10, a head member 30 having at least one electrically conductive brush 34A, 34B to engage the shaft. A pair of arms 40A, 40B each has a first end connected to spaced pivot points on the base member and a second end connected to spaced pivot points on the head member. A spring means 50 biases the head towards the shaft to engage the brush on the shaft. In use the base member, head member and spaced arms forming a parallelogram arm whereby the head member brushes contact the shaft at a constant angle as the brushes are worn.
