S800 b 20: Snap-action switch with pusbutton (standard) for side mounting onto a mounting plate
Flat quick connect terminals 6.3 mm x 0.8 mm
S800 b 20
Snap-action switch, pushbutton (standard)
Technical description
Snap-action switch with positive opening operation for the NC contact. The mechanism will break the circuit regardless of spring failure or contact welding due to a short-circuit.
Actuator travel
Acutator position Dimension X
Free position 8.85 mm ± 0.15 mm
Operating position 6.60 mm ± 0.35 mm
Release position 7.80 mm ± 0.35 mm
Total positive opening travel 5.85 mm
Total travel 5.65 mm
Differential movement (between operating and release pos.) 1.30 mm (typical)
Note:
*) If the switch is to be operated by a rigid drive shaft or setting, make sure to limit the actuator travel so that it does not fall below dimension x = 5.65 mmm.
To ensure the proper working of the positive opening operation it is necessary to depress the actuator to the point of total positive opening travel.
However, it must not be squeezed beyond total travel position!
Please note our accessories!
We also supply variants such as switches with longer roller levers or one-way roller levers with short or long bearing block. In addition to that alternative terminal types as well as reset springs are available.
