OMRON B3SL Series Tactile Switch SPST SMD 357gf 12V DC 50mA

The OMRON B3SL Series Tactile Switch is a surface-mount SPST tactile switch rated at 50mA at 12V DC, with an actuating force of 357gf.

Overview

This single-pole, single-throw (SPST) switch uses a middle-stroke mechanism that provides a crisp, positive tactile feel, giving clear user feedback during operation. The distinctive blue plunger assists with visual identification on assembled boards. Its sealed construction conforms to the IP67 (IEC 60529) standard, offering protection against dust ingress and temporary immersion in water. The switch measures 6.5 mm (L) x 6.2 mm (W) with a height of 3.4 mm and weighs 0.3 g.

Key Features

• Normally open (NO) contact configuration
• Round button, top-actuated design
• Maximum contact resistance of 100mΩ and minimum insulation resistance of 100MΩ
• Dielectric strength of 250V AC at 50/60Hz for one minute
• Sealed structure for high contact reliability in dusty conditions

Applications

Constructed for surface-mount technology, this flat-type switch supports automated assembly processes. It is suited to electronics that must operate reliably in dusty or harsh environments, where its sealed construction helps protect the contacts. Choose the OMRON B3SL Series Tactile Switch where a sealed, surface-mount tactile switch with a deliberate actuation force is required.
