Patent ID: 7372708

Claim:
A position detecting switch fixture for a cylinder, the fixture comprising: a mounting band to be wound around a cylinder tube; a pair of clamping reinforced plates opposed at both ends of the mounting band; a position detecting switch; a holder mounted to the mounting band, for holding the position detecting switch; and a clamping screw passed through the pair of clamping reinforced plates and retaining the position detecting switch together with the holder, between the clamping reinforced plates, wherein: the holder covering at least both side surfaces of a held section of the position detecting switch along the side surfaces, is installed between the pair of clamping reinforced plates to position-adjustably clamp the position detecting switch, and the clamping screw is also passed through the holder; and wherein: the clamping screw is provided with the following clamping positions: a first clamping position where, due to the clamping of the pair of clamping reinforced plates by the clamping screw, the base ends of the clamping reinforced plates adjacent to the cylinder tube approach each other and thereby the mounting band is temporarily fixed with respect to the cylinder tube, but the position detecting switch is not position-fixed; a second clamping position where, due to subsequent clamping of the pair of clamping reinforced plates by the screw, the ends of the pair of clamping reinforced plates opposite to said base ends approach each other and thereby the switch is fixed to the holder, as well as the clamping and fixing of the cylinder tube is enhanced; and a third clamping position where, due to further clamping of the pair of clamping reinforced plates by the screw, clamping regulation sections provided in the holder abut against each other to restrict still further clamping of the pair of clamping reinforced plates by the screw.
