IP67-rated tactile switches offer long cycle life

Update: June 10, 2021

E-Switch has introduced the TL6150 series of surface-mount tactile switches with three actuation forces that provide up to a 5-million life cycle. The series is rated for IP67 for moisture and dust protection. These tact switches target a variety of applications, including audio/visual equipment, computer peripherals, computer electronics, medical equipment, telecommunication devices, and test & instrumentation equipment.

Housed in a 6.2-mm square footprint, the tactile switches feature a soft silicon actuator available in 3.50 and 5.20-mm heights with gull-wing or J-lead termination options. The contact arrangement is SPST Off-(On).

Key specs include a 12 VDC, 50 mA contact rating and dielectric strength of 250 VAC for 1 minute. It also provides a contact resistance of 100 mΩ (max. initial) and insulation resistance of  10 MΩ @100 VDC.  These switches operate over an industrial operating temperature range of -40°C to 85°C.

The three actuation force options are indicated by actuator color:

  • Brown: 160 gf ± 50 gf (5,000,000 cycles)
  • Red: 200 gf ± 50 gf (500,000 cycles)
  • Orange: 350 gf ± 100 gf (300,000 cycles)

Travel varies with force:  0.3 mm (160 gf), 0.35 mm (200 gf), and 0.5 mm (350 gf). The devices are available now through the company’s distribution network.
