<p>A pressure mechanism is used for a safety cut out switch lock. It prevents the latch from engaging prematurely or inadvertently. The pressure mechanism consists of a latch (1) with a spring support (16) held by a fixing bolt (17). The special pressure spring (18) is seated on the clamping bolt. There are also two pressure rollers (19, 20) which are interlinked. The spring support is rigidly held in position. The rollers are mounted on one section of the pressure mechanism and the special spring is on the other part. The two parts of the mechanism can move relative to each other. The special spring fits around the two rollers (19, 20) and limits their movements.</p> |
