Omron B3SL Middle Stroke Tactile Switch

Tactile switches with rubber plungers suitable for industrial devices and other applications

Omron B3SLOmron's B3SL series middle stroke tactile switches are capable of operating in a temperature range of -25°C to +90°C. Their sealed construction conforms to an IP64 (IEC 60529) rating, which provides high contact reliability in dusty environments.

The B3SL is a 6 mm x 6 mm middle stroke switch whose rubber plunger provides a crisp click feeling when actuated and is suitable for appliance, industrial devices, and automotive control panel applications. Their switch configuration is SPST-NO with a switching capacity of 1 to 50 mA at 5 to 12 VDC and a contact resistance of 100 mΩ maximum.

The B3SL will deliver an electrical life of 100,000 operations minimum with an operating force (OF) of 1.96 ±0.49 N (200 ±50 gf) and a release force (RF) of 0.35 N minimum (35 gf). The B3SL-1002P (flat plunger type) has a height of 3.4 mm with a pretravel (PT) of 0.3 ±0.2 mm while the B3SL-1022P (raised plunger type) has a height of 5.1 mm and a PT of 0.5 ±0.2 mm.
