Contact Force
50-100 gf
Rated Current
5A at 250V AC
Mechanical Life
>100,000 cycles
Rotational Torque
10-30 N·cm
Contact Resistance
<20 mΩ
Dielectric Strength
1500V AC for 1 minute
Operating Temperature
-40°C to +85°C
标准
ISO 9001IEC 61058UL 61058DIN 41640

常见问题

What is the primary function of a contact assembly in rotary switches?

The contact assembly enables electrical connectivity by establishing and breaking circuits through rotating contact elements, allowing the switch to control multiple functions or positions.

How does material selection affect contact assembly performance?

Material selection determines electrical conductivity, wear resistance, corrosion protection, and mechanical durability. Precious metal platings reduce contact resistance while base materials provide structural integrity.

What maintenance is required for contact assemblies?

Periodic inspection for wear, cleaning of contact surfaces with appropriate solvents, and verification of contact resistance. Replacement when contact resistance exceeds specifications or mechanical wear is evident.
