ASSEMBLY AND INSTALLATION Please note: ZF snap switches should only be installed by trained staff. Generally, adherence to the required air gap and creepage distance must be ensured with suitable measures. These must also be adhered to for lines connected to the switch. If installation is to occur on a conductive surface, insulating panels must be used. Under some circumstances, their use is also required between switches installed alongside one another and plug-in connections. Switches can be installed in any position. Power transmission to the connections of the switch is not permitted. When fastening with screws, screws with a co-planar contact surface must be used. (e.g. in accordance with DIN 84, DIN 912). Smooth, solid surfaces are suitable for installation. Exceeding of the following tightening torque values is not permissible. We recommend trial installations. If you wish to install your switches using coupling pins, we would be happy to advise you on suitable parameters. If components are likely to be subjected to vibrations, we advise you to take additional measures to secure them. With solder connections, the product-specific solder recommendations must be heeded in order to prevent damage or destruction of the switches. Cleaning agents and solvents in proximity to the switches can impair their function, especially in case of watertight models. When using greases (especially mineral oil-based ones), we recommend consultation with ZF. The switching action may be initiated by a force acting vertically on the actuator, or by an angled actuation lever. The angle of the lever in relation to the top of the switch housing should not exceed 30°. The precise angle will also depend on the actuating speed, combination of materials, surface characteristics and so on. In case of auxiliary actuators with rollers or simulated rollers, steps should be taken to ensure that the lever does not impede its own action. This means that the direction of actuation should be away from the actuator‘s mounting point towards the roller, and the angle of actuation should be adjusted to allow for the geometry of the actuation system. We would always recommend a preliminary discussion with ZF. The actuator may not be pre-stressed when at rest. When actuated, the switch should travel well beyond the switching point. for at least 50% of the predefined overtravel, in order to ensure that full contact is made. It is quite unacceptable for the switch to exceed the specified overtravel or end position. Using the switch as a mechanical end stop should be avoided. A high-impact actuation of the switch can have a negative effect on the switch’s mechanical life.
