The Series 49-59 fits neatly into a ø16mm cut out panel no more than 8mm thick for the flying
lead version and no more than 1,5mm thick for the microswitch version (with sealing washer).
The switch body is fitted from the front of the panel and is locked down with an M16 nut using
a 20mm spanner. Panel sealing is achieved by the use of a sealing washer which is placed
behind the head of the bezel. To attain the correct sealing, the nut should be tightened to a
recommended torque of between 1Nm and 1,5Nm not exceeding 2Nm. Whilst the flying lead
version is now mounted, the microswitch still requires careful ‘snapping’ into its holder from
behind the panel.
Each flying lead switch is supplied with 500mm 24AWG 7/32 leads which are PVC insulated
and have plain unstripped ends.
The microswitch version has 2.8mm QC terminals which also provide the option to solder.
Double ‘D’ flats are provided to prevent rotation of the switch in the panel.
