Why choose this product?

• Standard SPDT (COM/NO/NC) wiring for flexible use in circuits
• Compact dimensions suitable for mounting on PCBs and small assemblies
• Load rating listed 1A/125VAC for low power switching

Installation and operating instructions

• Before designing the wiring, verify the layout of the COM/NO/NC terminals according to the markings on the switch body and the PCB installation documentation.
• When soldering, follow normal procedures for THT components and avoid excessive thermal stress on the leads.
• For reliable function, ensure correct mechanical seating of the control element on the switch button and avoid permanent overloading.

Safety notice

• The switch can be used in circuits with mains voltage (according to the marking 125VAC). When working with mains voltage devices, disconnect the power supply and follow the principles of safe handling.
• Observe the insulation distances and design rules of the device; do not exceed the rated load of the contacts.
