Snap-action switch, roller lever, angled mounting bracket

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.

Roller levers are used as auxiliary actuators to be operated horizontally by cam disks, driving or switching rods. Please refer to "Notes on project planning" in our catalogue D20e.

Actuator travel

Acutator position Dimension X
Free position 20.25 mm ± 0.35 mm
Operating position 16.60 mm ± 0.50 mm
Release position 18.40 mm ± 0.50 mm
Total positive opening travel 13.60 mm
Total travel 13.30 mm
Differential movement (between
op. and release pos.)		 2.20 mm (typical)

Note:
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.
