| 摘要 |
The invention relates to a device for determining the locking end position or the switching end position of a fluid-driven cylinder piston assembly of a switch turnout drive. Said device is provided with switches (30) which are dependent on the switching path and which have two interacting contacts (31, 32). One contact (31) can be displaced axially in the direction of the switching path of the piston (10) and an additional contact (32) is mounted in a fixed position. The interacting contacts (31, 32) are connected electrically to one another via a defined axial area and become disconnected when a contact (31) is displaced over a distance which exceeds the defined axial area. |
