Door limit switches for electrical boards, with a manual contact changeover function and automatic restoration of normal operation when the panel door is closed.
This limit switch has been developed by Stefan Electric for applications requiring a changeover in contact position without acting directly on the switch plunger.
It is particularly useful in electrical boards, where pressing the yellow button on the limit switch simulates closing the door. Assigned personnel can then work on the internal circuit to carry out modifications, maintenance and related tasks.
Normal operating conditions are automatically restored once the electrical board door is closed.

It is used in electrical boards where contact changeover is required without acting directly on the switch plunger. Its manual function allows the closed-door condition to be simulated during maintenance and modifications.
Normal operating conditions are automatically restored when the electrical board door is closed.
The rated current is 6 A at 250 V AC-15. The rated insulation voltage (Ui) is 690 V, and the rated impulse withstand voltage (Uimp) is 6 kV.
The switch has an IP65 protection degree to EN 60529 and permits mounting in all positions.
