PCB LAYOUT (VIEWED FROM EITHER SIDE):

SEALED VARIANTS:

This variant is available in two versions, fully sealed and top sealed. The top seal incorporates a rubber seal around the button

to stop the ingress of contaminants through this area. If the switch is to be activated by a cam, it would be advisable to do this

via a lever, as using a cam directly onto the button can cause damage to the diaphragm seal.

The fully sealed version has the top seal and also has integral leads ‘potted’ onto the terminals. This version is rated at 125°C.

There is also a derated version, to 105°C, available. This has the advantage of being lower cost than the standard version. If you

should require more information on this version please contact the Sales Office.

MOUNTING INFORMATION:

PCB Terminal version

This version mounts directly onto a PCB which has been drilled as illustrated. To ensure a tight fit in the PCB during handling

and flow soldering operations, the switch can be inserted into the PCB, and then the terminals may be splayed by 30° in an

alternate fashion. The terminals have an in-line rectangular cross section to facilitate this, and to eliminate the reduction of

creepage distances in the fitted application.

Solder, QC and flying lead versions

These versions have two mounting holes that accept M2,5 screws (with anti-vibration washers if relevant) tightened to a

maximum torque of 0,3Nm. One of the mounting holes is slotted, to allow for a tolerance between the screw centres of ±0,15mm.

If the switch is being mounted onto a metal surface, a separating insulator is recommended on the solder and QC versions, to

ensure bare wires cannot make electrical contact.
