Apparatus ( 2 ) for use by a person for dissipating an electrostatic charge, comprising a body portion ( 4 ) made of an electrically conducting material for being held in the person's hand, a contact portion ( 6 ) made of an electrically conducting material for contacting an object ( 8 ) in order to dissipate the electrostatic charge, and an intermediate portion ( 10 ) made of an electrically conducting material positioned between the body portion ( 4 ) and the contact portion ( 6 ). A resistor ( 24 ) is mounted on the intermediate portion ( 10 ), a first leaf spring ( 28 ) is mounted on the first part ( 16 ) of the intermediate portion ( 10 ) such that the first leaf spring ( 28 ) causes electrical contact between a first lead ( 30 ) from the resistor ( 24 ) and the interior ( 32 ) of the body portion ( 4 ), and a second leaf spring ( 34 ) is mounted in the recess ( 14 ) in the contact portion ( 6 ) such that the second leaf spring ( 34 ) causes electrical contact between a second lead ( 36 ) from the resistor ( 24 ) and the interior ( 38 ) of the contact portion ( 6 ). The compression of the second leaf spring ( 34 ) provides both secure electrical contact and a constant upward force thereby preventing the loosening of the pair of screws ( 22 ) located between the intermediate portion ( 10 ) and the contact portion ( 6 ).
