Relay |
摘要 |
For the purpose of testing a relay, a safety relay comprises a key (12) arranged in a housing cover and which acts upon a lever (38) pivotally mounted on the inside of the housing. Due to the pivoting of the lever a movable switching contact carrier of the relay is moved. To avoid excessive deviation of the switching contact carrier through excessive lever force and therefore a possible plastic deformation of the contact carrier springs, the force which is possibly applied to the switching contact carrier is restricted by a U-shaped spring (40) held by the lever (38). A pressure leg (48) is biased by a latching lug (52a, 52b) supported by a peg formed as one piece with the lever (38). Consequently the switching contact carrier is moved via the spring with only a predetermined maximum force, so that a deformation of the springs supporting the contact pieces is avoided and the contact pieces maintain the required specified contact distance. <IMAGE> |
